Xena...you're completely justified... :-) I too would do the same thing if I felt uncomfortable going in a particular store. This isn't down to laziness at all. I left a store just yesterday because I was being followed...

I'm talking about the kind of people who can't be arsed to go through the drive through at McDonalds but park up outside and honk for someone to come out. That's just wanting to jump the queue.
