Business owners that do that had better be very careful and keep plenty of documentation. There are legal "tests" (read requirements) that must be met for those lunches, travel, cars, computers, etc. to be considered an expense. In many cases, any "non-business" use/benefit/enjoyment renders the entire expense not a business expense. Yes, it is not so rare for small business owners to play loose with the rules. And then they get audited and end up paying a lot in back taxes.
