Obviously never worked retail
"Getting a free meal once or even twice and then losing somewhere I enjoy going to a month later is not exactly doing me any favours. I'm pretty sure most people would see the logic in this."
There is a subset of consumours out there that love the free meal, weather it be an actual free meal or a free gift voucher etc.
Unfortantly they have been bred by companies and managers ignoring the staff who say "this is BS/he has no case/it was his fault, he broke it/its not broken " and saying "yes, sir , no sir, 3 bags full sir"
While its a good thing the site is there and yes people should see the majority of reviews, amazon/ebay reviews only really work cause you are pestered to review on a sale so you get both the GOOD reviews and the bad
Remeber (and this is important and will be shown i think), people kick up a fuss when they are annoyed about something, are nice and quite when they are happy and contented (basically people will be more willing to write complaint letters than tahnk you letters, another thign people working in retail will know)
