The guy in the Google story had an excuse: a mental disorder. The guy at the bar was a garden variety idiot.
Well I will add this if you ever Seen a coin swallowed and gone through a digestive system it would be black not toned. The stomach acid does a heavy number on medal. And even so .....the exit isn't always a fun time.
This reminds me of a story a friend who was a vet tech told me. Well a couple brings in this large breed dog who is having issues....... So after an x ray they found out that the dog had eaten something and it was blocking it bowels. So surgery is done.....and the dog does just fine! The wife came to pick up the pup and after paying a nice sum of money.....was handed a small baggie with the item the dog ate...... Well this is where the story goes south......as in the baggie was...... A pair of leopard skin panties...... at which that time the "wife" said they aren't mine! We'll from that day on the practice never gave back to the owner / owners any item or items taken from a pet. needless to say someone other than the pup was in the dog house.
