As a BW whose H cheated with a co-worker and has similar boundaries with H now, here is my take...
Work is not just 9-5 in the office work in most companies. Coworkers become friends BECAUSE the personal stuff gets mixed in. There are happy hours, business trips, dinners, conferences, etc - and they are part in parcel these days of building "culture" and "team". I had zero problems with all of the above pre DDay because I thought my H had BOUNDARIES (not to mention integrity, respect and a whole host of other character traits).
Now that he has proven he has a shaky history with boundaries, we've made provisions to keep ME comfortable. I retain the right to change and adapt as he shows me he HAS boundaries, but for now, he doesn't have solo car trips/rides, text threads, or meals with females.
Any meeting IN OFFICE meeting would obviously be ok. But let's be honest. A meeting in an office is business, purposeful. A "lunch" with someone you are comfortable with would be less so - it's just the nature of the beast. A car ride, same story. You don't keep to business. It allows for a slippery slope - and it's exactly how my H's affair started. Took two years to go from friendly banter in office, to texts, to suggestive emails, to hugs, to her kissing him on a work trip, but it happened (and obviously boundaries are more easy to ignore with alcohol and out of town spouses).
Now I'm not saying that all relationships would be this way, bc boundaried people wouldn't have an A, but I think we ALL have a little wayward in us. It feels good when someone compliments you, flirts with you, or validates you. Given the right situation, and lowered or shitty boundaries and POOF - bad things can happen. Especially when the situations are with the same person over and over again.
Anyways, this is my long winded way of saying that your reaction is normal. The panic at what to say in that situation. Your wife's reaction is also normal IMO. As BSes we wonder how our WS will react in certain situations to honor us, and hope that they'll choose us. When they don't, it's upsetting. Each data point from here on out will either build trust or take it two steps back.
We've actually had this happen since DDay. A few months after DDay 1, WH was stuck giving a female co-worker a ride to the airport. His boss asked him to do it because he was the one with the rental car. He panicked but didn't know how to say no. So what he did was text me right then and told me what was happening. Obviously I said that's fine. Him being proactive and thinking about me and boundaries is what I need. Extenuating circumstances happen! The moment he got through security, he called me and we talked until he boarded. (He also said he kept any personal convo to a minimum and steered things back to work every time she veered off.)
I think it helps to practice these situations too. Have an answer ready. I agree with Dee that lying is not a good alternative, but you could always say that you have some calls to make and could she ride with someone else? Not a lie if you call your wife?
I also think communicating BEFORE things happen is the best defense. I literally had no angst about my WH's giving his co-worker a ride that day. Now, had I found out he did it later? Or if he hid it? THAT is wayward behavior. (In fact he DID do this with a meeting later after DDay 2 - a superior asked him to meet for coffee/business in the lobby of a hotel and he didn't tell me. I knew the meeting happened but she had switched locations and he didn't divulge that info, which is basically lying by omission in my book. He KNEW that I wouldn't like it and didn't want to admit that he'd broken a boundary on the first international trip since DDay 2. (Even though again, I would have understood extenuating circumstance - THAT one set back my trust level.).
I think it's great that you are aware and still working after 7.5 years. That is a great sign for your commitment to being a better husband and partner.
