My missus has worked in two of the stores for 8 years now.
Don't worry the good meat packs rarely make it to the view of the general public.
We give her a bit of stick about working there sometimes which is a bit nasty.
Totally agree they sell some dead set rubbish but there are some good buys as well.
I love my gherkins and other preserved stuff like Sundried tomatoes so it's comes down to what you actually buy I think.
