Well, there are a couple of issues with your logic. First, in the state of TN there isn't a 'bar' liquor license. With the exception of special events, and 'other' (which are strictly limited to certain government owned/operated and non-profit organizations, large tourist resorts) there are no 'bars' in the state of TN. So, virtually all of those 'pure bars' and saloons have been issued 'restaurant liquor licenses' under state law, and as such meet all the requirements of this bill as verified by the state.
See, TN law requires all 'restaurant' liquor licenses to serve food, and provide at least 75 seats for their customers to eat. And they verify this requirement as part of issuing the license. So under the current wording of this bill, with one small exception if they've been issued a restaurant liquor license they meet all the requirements (note, liquor license requires you to serve food 4 days a week not 5, so a very small number of businesses could have an issue if they're only open 4 days a week, or only server food 4 days a week but I suspect that is very rare).
I don't think anybody here is suggesting you go out and get drunk while carrying... but I can think of some traditional 'bars' I might want to go into from time to time, and enjoy things other than drinking. Maybe, I want to play darts, or billiards with some buddies after work... there are lots of valid reasons to go to a 'bar' after work and not drink.
