I totally agree Jupe - I wish I had come up with a long term excuse, but in the moment it was all I could think of, and I was panicking.
I can just always say I'm on "meds" that don't allow drinking - because it's actually the truth (I'm on anti-D anti-A medication and you're technically not supposed to drink on it - although I always did before.)
Now I've convinced him we should go for sushi (I LOVE sushi - not only the food itself but the fact that it's a totally acceptable work lunch that DOES NOT involve drinks - other than matcha tea at the table & water
)
Yay sushi!!
