Not a pet peeve, but annoyance

Line up etiquette

Sometimes, I'll be in line to get my afternoon coffee at Tim Hortons and the person behind me seems to think I am not there. Either that or they really like how I smell. But basically they seem to have no sense of personal space, their own or mine. I can almost feel these people breathing down my neck and it is very disconcerting. I can't even turn to look to my side without bumping into them. What is the purpose of this? Whether they stand 5 cm from me or 2 feet away, they will not get served any earlier. Nor will someone else take their spot unless they are standing somewhere completely different. Why do people do this? What happened to respecting someone's bubble?
