None. The only thing I was asked that was a deal breaker, was if I would work an occasional weekend, if needed. The correct answer was "Yes," but I've only worked 8 weekends in 8 years, and that was only for the annual trade show. The trade show help generate more sales, so the more customers that show up, the more money I make, so this reasonable time investment is a mild and smart time investment in the success of my career.
