Here in FRance (live in Switzerland, but very close to border) they really are fast at the tills - and I just cannot cope. I've several times asked them to slow down, and they've explained that they are timed and get told off of wages docked, if they are slow. The one nearest to me (DIA, as Spanish chain) which I've stopped using for this reason- having discussed it twice with the store manager- who said instructions come from Head Office, and his job is on the block if his staff do not check out as fast.
There is no packing service and no help available at all, in any of the large stores to get stuff to the car and lifting heavy stuff (Leclerc, HyperU, Lidl, Géant, Atac, etc). The other day I bought a huge bag fo wood pellets for the cat litter- and could not lift it out of trolley and into car- I had to beg a young chap to help me in the car-park).
