Corner Bistro, a haven of tightness except for this

Ah, the anticipation of the Bistro Burger.  You try not to think too much about it from the time you place your order to the time you see your waiter come back with your eight ounces of heaven.  Then your mouth starts to water as the moment has arrived... only to find a latex glove in the burger?  Unacceptable.  The situation is only made worse by the fact that you now have to wait for a replacement while thinking about how weird and disgusting this is (presumably a bare hand that was previously sweating profusely inside the glove has touched your burger) but also that it is seemingly impossible to misplace a latex glove.  Why was it taken off?  Why was it so easily forgotten?  How did they manage to turn what should be a symbol of cleanliness into this?  Why do I have so much time to think about this before the next burger arrives?  When can we go back?
