Tipsy customers

I have a rather sensitive nose. We sale cinnamon brooms and I ask people to leave them in their carriage because they make me sneeze, give me a headache or mess with my breathing in large quantities.
I mention it because I notice the alcohol on people’s breath quickly. One supervisor came in one day with it on their breath, but the worst are the tipsy customers.
One woman put some stuff on the cabinet to be rung and when that was done she just gazed at her cart. Then looked at me. I asked if they were separate sales and she said no. She moved some stuff, then checked the subtotal and forgot she still had stuff to unload.
Meanwhile everyone behind her feels sorry for me, who has to get and keep her attention, while disapproving of her. Here’s a hint: If you want to do shopping and drink alcohol in the same day. Do your shopping first!
