I had no idea this is apparently rude?
Today while in a cafe queue I said to DH "go and get a seat while I pay". He looked horrified
said I was effectively "pushing in front" of those queueing in front of us and we shouldn't sit until we had ordered and paid.
I don't really agree and think everyone does this if they are in a group (after all if a family of five go in are they all going to stand in a queue together? What if everyone did this, the queue area would be overrun?!) and it's neither polite nor impolite, but he was insistent.
Who was BU?
