Will you just do what you should
I work in catering currently in customer facing role. Why do people have to do things they know they shouldn’t and make a hash of everything. If you have not been trained to use a machine don’t touch it. The rules are there for a reason, normally a legal reason to do with health regulations. Don’t use a set of tongs designated for meat to take veg and most of all don’t use equipment designated for nuts with anything else.
