I like some things about Waitrose, loathe other things.
Love:
The hot chickens are yum (Tesco's are vile)
The fishmonger's in our local one, although pricey, is very good - very fresh produce and the fishmongers are knowledgable.
Their essential range is good value and pretty good.
Loathe:
They are cold. Always so very cold!
Over-priced fruit and veg which really isn't any better than any other supermarket (...and is always freezing cold to boot. See above)
Ridiculous amounts of poncy packaging they use. Seemingly everything comes in a foil container, double wrapped in cellophane and with a poncy cardboard sleeve.
The 'bakery'. The bread is alright, but the baked goods are awful, bordering stale. Solid cakes, rock hard iced cupcakes. Yuck. Sainsbo's bakery vastly superior.
My local one is full of wax-jacket wearing Tory grannies with lemons up their arses in their mouths.
