I don't like places that are always refilling iced tea; I like my iced tea a certain way
I hate when anyone says Ice Tea. It's Iced
Tea or Iced
Also, as someone who's worked as a musician in hundreds of bars and restaurants, hear's a list of stuff that drives me crazy enough to kill or at least seriously maim:
Leaving the house music on in the bar while the band is playing in the restaurant
Leaving the house music on but just lowering it
Having 100 televisions tuned to 30 different channels. Stay home and watch Law and Order or don't have a band at your bar. Sports Bars are the exception, good luck competing with the 50 foot Wall of Distraction.
Karaoke machines. 'Nuff said
Guitar players...oops, that wasn't really germane to this discussion was it. Oh well, it's true. Tune up and turn down please, my tinnitus thanks you.
I have a hundred more but you'll all just think I'm bitter :P
