Dear customers, on behalf of someone who worked in the service industry for many years: be kind to people who work in service. Their jobs are difficult and they deal with a lot of bullsh*t on a daily basis. Also, their job is literally to serve you — and if you mess with them, they may just serve you a freezing cold dish of revenge.
Just happened. Its towards the end of the business day for my bottle shop. I'm running low on certain items of change in the register, so I am asking for people to pay with exact amounts, or by card. Enter Karen. Karen comes in, and purchases a $7 bottle of wine. If she was to pay with a $10 note, that's ok. But she decided she wanted to pay with a $50 note. I asked her if she had anything smaller, and she claimed she didn't...yet I could see the edge of a $10 note in her purse.
