Yeah, the writing on this post is pretty bad. Like...have you worked for this company a few times before? or not? If a person has a college degree (I don't), getting feedback about writing for a writing job shouldn't be so hurtful.
I understand that some companies have odd style guides, but they do provide samples. It's also pretty standard for any food (even fast food) to report how many minutes until you received your order. If you have not done much food, you may want to check out A Closer Look. They have a lot of great restaurants and give helpful guidance at every step. Not every company is working with you to accept the shop. Most will, but it depends on how close you are to a usable report.
If you want to keep shopping long term, there are plenty of simpler shops you can do to build up to a full, formal meal. I would recommend doing more casual service dining and some separate bar shops to build your skills. It comes together pretty easily but there is no substitute for practice. If you just want to work as an occasional shopper, you'll still get good value for putting in the effort.
