So They Left
The waitress returned with the same drink in her hand and handed it to the friend. She informed them that the bartender said the drink was fine. So, in other words: I couldn’t be bothered to make your visit enjoyable; just drink your drink and go away.
The waitress pretty much relayed this statement to the group of friends. They had two choices: either try and make the best of the disappointing drink in a bar that clearly didn’t want them, or they could leave. They chose… wisely. The band got up and left. We hope they didn’t pay the bill, let alone give the bartender a tip!
