No pass from me. I was a Girl Scout. We asked everyone on the way in, and assumed they were smart enough to figure out that we were still there on the way out if they wanted. Actually, we rarely asked, since we set up a table, and that was enough.
I would have talked to a manager. I rarely buy from people like this because I hate feeling pressured to buy something overpriced that I don't want anyway. But, if they are rude, I feel like they should be called on it.
