Can't speak for "others" Lidl are not involved in the legalities save they seem to have sold their birthright for a mess of pottage subjecting their customers to such appalling treatment at the hands of Shyster & Co
The next Lidl I see that has handed their parking control over to Shyster & Co will be the last time I go near it.
I can only assume the powers that be at Lidl don't realise they are putting their business in such jeopardy.
It takes 10x as much expenditure to keep a customer than it does to get a new one. Times are hard and freinds are few.
