The scene: Busy cafe this morning. It's a small cafe with only eight or so tables in the middle of a shopping centre, with people walking past on either side of the tables. On either end of the cafe, two long tables are set up that can seat twelve: six each side. Today though, a group of Mums, Grans and kids set up so they were sitting on one side of a table only.
Now, the cafe was busy. Someone did actually approach and ask if they it was okay if they sat down at the table, to be met with, "No, sorry, there's no room!" AIBU to think this was a little unreasonable (and giving mothers a bad name?)
