My sister was unemployed for the first year of Covid. Then she was finally hired for a waitress job which she has done for over a decade.
She owns a pair of black non-slip shoes and grey non-slip shoes. First day on the job they were appalled she didn’t show up in white non-slip shoes. Which you wouldn’t buy unless part of the uniform because in the restaurant they get really dirty and scuffed up easily. No one told her she had to have them prior.
The other thing is we live in a very remote tourist area with no shoe stores or uniform stores for 100 miles. So they sent her home for the day. I had to buy her white non-slip shoes online with overnight delivery for her since she had no money. And it took a couple days to come.
She explained to them the shoes are on the way so they let her wear the grey ones in the meantime. I’ve worked in places in the past that give you a little leeway on dress code the first few weeks on the job.
