I had a whole flurry of snowflakes in 2 days of Christmas markets.
There was a booth shared by a woman with felt clothing and another with knitted garments. I very politely asked a lady being shown the felt things and blocking the entire entrance if I could get past her. "No. Not at the moment." I don't know which vendor's jaw hit the floor first." The felt lady moved her customer into the HUGE gap to her left and we got past easily. Knitting lady was still speechless when we left.
Different market, me on the other end of the same question. The big markets have wooden huts and the one we wanted to look round was packed. They were monitoring people leaving and entering to try and make it bearable. We were in the middle of the hut, like sardines, when a voice barked in my ear, "I need to get past!" When I told her that we were all heading that way she shrieked, "But I work here!!!" Maybe lady, but I can't dematerialise. No, I didn't say that but I was tempted.
Leaving town, traffic was bad, so it was hard to get out of the way of the ambulance but we all managed. And the snowflake who tried to use the gap being created for the ambulance to get out of a side road was blocked so he couldn't. Really, who thinks that's a good idea?
My favourite - hubby let the above snowflake in front of him. The lady following in a very expensive car stayed where she was. Imperiously raising her hand to order us to stop, ( think traffic police), didn't work. We solemnly mouthed, "No", to her. By the look on her face, it wasn't a word she'd heard before.
