scotch. Those errors are rare, although these four reasons you should never open a bar tab are far more common.
You’ll have to wait for the tally. Say you’re done drinking and ready to go. You pay your tab and skedaddle, right? Wrong. When you open a bar tab you have to wait until the bartender has a moment to tally it up, hand it over and run your payment through. If you wait until closing to tally out, you’ll be waiting behind handful of other goofballs who also thought it brilliant to open tabs. By then your buzz may have wore off, but you can’t even add another beer.
It makes you look broke. Bar tabs are typically for the very rich at ritzy places or for the broke dude who spends his entire paycheck before he even gets it. We’re guessing you’re close to the latter. Opening a bar tab makes your station known to everyone in the bar, including that cute chick over there who was going to let you buy her a drink until she realized how broke you are.
