Theft is #1. That's why you are watched closely if you are not known. Customers thinking they know everything, being loud and obnoxious, complaining about prices. The ones that come in asking if we carry Cuban cigars. The customers that come in and want a suggestion for something new but almost always goes another way as they physically turn their nose up at my suggestion. Customers that think a smaller ring gauge cigars are feminine.
The one that ranks up there with theft with me is when customers come in and say, 'I smoked this one cigar last week in Indiana and the band was red. Do you have it?' and expect me to know what it was! WTF?
