Well, yeah. Probably because they’re complaining to posters here, rather than to someone that can do something about it.
I mean, what’s more likely to work, walking into a shop and politely asking to speak to the manager or hanging round the side doors yelling at anyone walking in and out?
Seriously, try Twitter, e-mail or even @-ing the staff in a post. But having a big old sook about it to anyone wandering past here is, well, mostly only going to amuse me.
