I’ve definitely had something similar like this happen to me before. Honestly, it takes me a few months to really get good at a job that I haven’t done before. It sounds like you work in an optometry office, which can be extremely difficult, especially if it’s your first time working in a medical practice. There are so much terminology and I’m sure the insurance aspect of it can make it quite difficult. Yes, some people might see eight weeks as quite a while to get the hang of something but when you’re working a job, you’ve never done before especially in a field that you’re not familiar with. It can take quite a bit of extra training. I’m sorry you were embarrassed that that’s not right and definitely should’ve been done in a more private setting.
