My bank only offers drive through service these days. There are two 'stations' that service customers. Both were occupied, with no one waiting when I pulled up. I put myself in a position between the two, waiting for one to open. I was there about 10 minutes. A mini van pulls in behind me and starts on the horn. I shrugged my shoulders and ignored him. He pulled up to my right and tried to ease past, with about one foot of clearance. I had my windows down and asked him WTH his hurry was. He said there were 2 lines and I should pick one. I said there were 2 windows and one line, similar to the current grocery store situation where everyone lines up behind one another and go to the available cashiers in turn. I also said I had been waiting for 10 minutes and should have the benefit of the next available teller. A window opened up then and I drove there to complete my business. I'm not sure there is a right way to act politely in this situation, but I favor my approach. Any thoughts based on your locale and norms?
