If it’s anything like my time on the night shift at a grocery store, there’s probably one person that’s been there for decades and only has to pack out one aisle of pillows, or some other bulky and light stuff, while everyone else has to cover 3 times as many shelves, with smaller and heavier items. But since that person has been there forever, they’re one of the holdouts with a decent contract that makes several times more an hour than anyone else, including the shift supervisor, and actually has decent benefits.
Nope, it’s true. When I went for the first time a couple of years ago, my bank decided I needed more £50 notes than anything, and I got several “Wow, it’s been a while since I’ve seen one of these,” comments when I used them.
Also, fwiw, depending on where you’re heading in the UK, cashless payments can be way more prevalent than they are in many places. I’ve been to multiple bars in and around Manchester that just didn’t accept cash, and would bring out a card terminal to tap for every £2-3 beer I ordered.
On the other hand, bring a coin purse or something with you, because when you do use cash, you’ll get a ton of coins back, and it becomes a pain to have rattling about in your pocket real quick.
