What bugs me is when I want to buy a bag of Hula Hoops or Quavers (my faves) and they only sell them in those supersize bags that would feed a family of Ethiopians for a month.
The meat flavours are not ones I tend to go for. I can imagine sprinking salt or cheese over crisps but meat seems a little strange. Maybe that's a common feeling so they don't sell as many ? (Probably none of the actual flavour ingedients used anyway.)
And why does no one stock Branston flavoured Mini Cheddars? They're still occasionally around as part of those big 'variety' multipacks, but not as individual packs. Grrr!
find out who does the purchasing and ask them, perhaps meat flavoured crisps didn't sell as well and they ended up with a surplus, maybe the purchaser has an irrational fear of meat flavoured products
OR they're doing it deliberately to annoy you and they are on sale, just not when you go onto the canteen
