I had to do that once; my T forgot the keys to the office and we ended up in an out-of-the-way, mostly empty cafe doing our session! It was difficult; trying to talk about important stuff but making sure it wasn't too deep so I wouldn't have to cry, etc. She let me order first and I ordered a soda and a sandwich I think and she only ordered hot tea! Talk about embarrassing, to be eating while she was not (no talking with your mouth full!) and we got to the end and found out the cafe only too cash if the bill was under $10 (ours was) and, together, we did not have enough cash to pay, LOL. It was an adventure I'll remember all my days.
