A few times in my life I encountered a system where 1 is labled "Satisfactory" or something similar and 5 is "Perfect" or similar.
In those cases I either refuse to rate or rate a 1 no matter how it went.
I think the system should always be so that 1 is absolute dog shit, 3 is no complaints, 5 is exceptional
I hate that 5 is anywhere from "just okay" to "amazingly exceptional" and you just can't know which it is
