My husband wore some shoes out the shop once and handed the mortified shop assistant his dirty old trainers to dispose of. I was actually quite embarrassed but he was like "that's what we did as kids".I did think about kids shoes when I typed that, but clearly they've already worn them around the shop in full view of the salesperson, and they tend to ask you if the child wants to keep them on so I don't think that counts.
You wouldn't try on a pair of shoes in New Look or Next, then walk to the counter in them... although I now have vision of if we did do that, then having to slam your foot up onto the counter so they can scan them
You wouldn't pick up a roll or sandwich in Greggs and eat it while you queue, so in my mind there's no difference.
I can see your point in that you've at least scanned something, but I still wouldn't do it, or give in to my kids whining because you still haven't actually paid
It's actually normally me that takes a drink to have while I walk round the shop. My 3 year old I'll usually reason with. But when the 1 year old sees his baby crisps go in the trolly, he goes psycho. So it's easier to just give him the crisps then have a hysterical baby in the trolly screaming the shop down.
Once he went made at the till because he wanted the oranges on the next conveyer belt over. The kids a bit nuts
Drives me mad - she earns a really good wage and owns a flat she rents out and has a husband with a good job as well, saves loads every month …..yet turns up late to a cafe date and will drink the dregs from someone else’s pot of tea and eat the cake someone left. I mean, fair play if you have the willpower to save, the motivation to be sensible etc etc, but don’t be a tight arse who won’t even spend a fiver on a cuppa and a slice of cake once in a while! Still I guess it’s how the rich get richer
