I was doing a shop where I had to get an exact timing from when I stepped in line to when I was helped. I get in line and there is someone being helped, 1 person ahead of me and 1 man behind me. Three people come in next and start chatting with the girl in front of me and it's obvious they are together. So the man behind me tells them if they are together, that they can just go ahead of us and get in line with her. Thinking this would really mess up my timings, I had to look at them and say, "No, I'm sorry, but you can't go ahead of me". Awkward silence and felt like an ass, but she should have offered to go back with them. It almost distracted me from what I needed to do next. They dined in also and I seriously wanted to slip them a note explaining myself but didn't. Turned out, I re-arranged a room when I got back and somehow lost the receipt so the shop was not accepted anyway!! LOL I offered to re-do it and will try again. What would you have done in that split second? I guess i could have allowed them to go and explained it in the summary...
