Got precious little choice, and when I do go I have to put up with idiots and their trolleys you wouldn't give a driving license, plus o.a.p.'s who should delegate the task to somebody younger.
Considering what I put up with, every Friday is black Friday. I don't think dropping bombs on them would change much, either, they'd still get in the way trying to get out! Even splitting my shop between Thursday and Friday hasn't improved things much, but it's an idea I could take further.
If your shopping is worth £50 or more most of the supermarket chains here deliver for free. Is than an answer?
