Hate Sainsbury's. It's shit.
Sorry op I apologise in advance.
Products, customer service, price and their online delivery service is absolutely diabolical.
Had an online delivery once and once only. I shit you not; the delivery guy was unpacking the groceries with raw chicken juice absolutely DRIPPING from his hands.
It was a raw chicken I had ordered and the bag had split. It went EVERYWHERE. It had dropped all over my other groceries and he proceeded to touch all my products and never even offered to take them back.
I forced him to wash his raw chicken juice covered hands in my kitchen sink and then had to thoroughly wipe over all the contaminated products he had left when he had gone.
Disgusted was not the word and the customer service when I complained afterwards was absolutely disgusting.
Worst supermarket. Ever.
Sorry op. Rant over
