I try not to judge an entire business (especially one I've dealt with for years) on one bad experience with one employee (especially a relatively new one).

Every place I've ever worked, and every business I've ever frequented has one or more people that are hard to deal with.

It's just a question of how "bad" are they and how many of them are there.

In the post-covid tight labor market some businesses are having to employ people they might not normally employ because they need the bodies and don't have many options to choose from.
