Everyone has good days and bad days, however even the most serious vendor offence against a customer I have seen here would not deter me from that vendor.It is clear they all are honest and service can vary for all sorts of reasons..reasons that may be irrelevant on the day a decision is to be made.. if a newcomer wants to know where to buy something why not have them ask the troop here... great excuse for a chat and a story or two... Although the idea has merit and is in essence a good idea it could corrupt into almost a criminal record approach.. good things (ideas) corrupt worse than bad things so they say so the better the idea the more fear of absolute corruption.
Also how could such a system manage staff changes something of particular and timely relevance to determining a altering a rating system.
I think we need a committee to look into this further
