After attending my granddaughters graduation. I decided to have a nightcap before returning to my hotel. I went to D@Bs. I ordered a drink that totaled 7.20 gave the barmaid a 20 dollar bill. She mistakenly entered it as a 10 dollar bill. When I stated that she handmade a mistake. She called the mgr. They supposedly closed the register to count her receipts. I had just came from the bank ATM and did not have any 10 dollar bills in my wallet. After a short while the mgr. returned and stated that there was no mistake made. I would have ordered another drink but instead I left a 2.00 tip. and left the bar. I hope the 12.00 the barmaid made helps her. There will be no more visits to D@Bs for me.
