Noticed there is two types of Adli , the blue one which we dont get in the UK , seemed inferior the normal one.
There are indeed two Aldis. This came about because the chain was initially founded by two brothers, who later went their separate ways after a disagreement, and in what might be termed a very Germanic manner both carried on with their basically identical supermarkets but dividing up (by areas of Germany, and by country) which would be each of their territories. I believe that, many years on from this, they do agree enough to share some supply chain, though, sort-of in the manner that Waitrose and Booths do at the other end of the market despite not being actually related to one another other than being a similar type of store.
In Germany it's Aldi-Nord and Aldi-Sued - north and south - and there are only a few cities where you get both. In the UK we have Aldi-Sued. The other one (which is more white than blue in terms of the logo, ours is blue) doesn't operate in the UK.
There's a bit more detail on this in the Wiki article - but as I said there is something incredibly Teutonic about the way it happened.
One thing Aldi lacks is self scans , can be annoying when you have to wait behind trollies when you have only a few things .
In most Aldis I've shopped in, the unwritten culture is that if someone has a few items and you have a trolley-load you let them in front. This works very well when people play the game. Indeed, Aldi works very well generally if you play the game - the speed of throughput at the tills requires you to play along by throwing your stuff back into the trolley as quickly as you can rather than faffing with it, and to have your cash or card ready. There's also something quite Teutonic about that - working with the system for the greater good - and when people play along with it it works incredibly well.
