gave me a speech about how incompetent retailers like me are the reason people HAVE to buy on-line to get what they want. Before leaving, he told the next person in line that she was crazy to buy the book she was holding at full price when she could save "a small fortune" buying it off Amazon.
And, yes, I get people like this on a pretty regular basis. One guy spent close to an hour in the store one day, asking me what I was going to do for a living once digital comics put me out of business. Then again, he was in the printing business before his shop closed down, so maybe his own bitterness was showing.
