Someone I know has just been caught in the one in Spennymoor, (co Durham). Don't know exact details, but they have put a time limit on, 40 minutes I think. She'd taken someone disabled to shop, who took too long!
Wow that doesn't seem like good business. I would go in shop then run out time and just leave my cart full up and just say oops ran over I will have to leave without actually buying anything. If a bunch of people do that and the store has to keep restocking the items and losing customers they will change that limit. I need at least 2 hours for a full shop.
Tell them to email in to Aldi customer service, I got a ticket at my local store a few years back now but I had twins they both decided to have several melt downs that day I explained all this in the email and they dropped the fine I actually wasn't expecting them too either.
