Waiting In Vegas

After serving four older ladies I dropped the check on their table, advising them that I would pick it up whenever they were ready.  I then watched them try to figure out how much each of them owed for over $25 minutes.  Each of them were throwing money in a pile and then taking it out again.  It was hysterical to watch.  The best part was that each of them had almost exactly the same thing and owed more or less the same amount.  Even with their regular sized calculator, it still took 25 minutes! After all this I was pretty sure I was getting a shitty tip but they actually left me $20 on $80.  I think they felt bad for being unable to perform basic math.  Deep down inside, I hope they were drunk.
