You are all so lame! The girl probaly made an honest mistake, I'm sure she isn't in the coffee pouring field in hopes of making manager someday, and she most likely needs to cash out or pay the balance. Secondly, if you don't want to tip, don't, but if you tried parting with fiftey cents every now and then, you'd find the service you recieved would be much better and they'd probaly not screw up your change !!!!
