Huge was thinking very hard :
An idea that would stop me going there. We've only been in the local
Aldi once, in search of decaf coffee, which they didn't have, so
we left.

It works rather well, the checkouts become busy, they put more tills
on. As it quietens, staff are diverted to topping shelves up. All staff
wear a communication system so can quickly help each other out. I find
them usually quicker than Tesco/ASDA/Sainsbury etc..
