to avoid

Absolutely appalling service - went there at 9 for dinner, knowing that the place closes at 10. when I got there, the staff had closed the restaurant and were packing up, and I was told that they’d closed up because there were no customers. Flora (possibly not her real name) told me that her boss had approved the early closure.

When I pressed further and showed her the official closing time, and told her that there was no reason to close the shop now that there were customers, she had the temerity to inform me that the restaurant was supposed to close at 9 just today, and that it closed at 10 on all other days.

I recommend against treating your potential customers as fools.
