So I appreciate there are rules. I've been to several shops which have had the 2 metre rule and people have been very good with it.
However I went to Aldi 2 days ago.
There were couples in the que, a few people with kids.
There were markers on the floor and someone letting people in when other shoppers come out. Very normal upto now.
However the guy at the door was saying you aren't allowed to shop as a couple so only 1 person per shop.
People who had come together (for whatever reasons) were seperating and getting their own trollies.
This guy was then saying 'I saw you come here together /getn out of the same car/Talk to each other.. You're not both coming in'
He was making plolder people stand out in the absolutely blazing sun) a older couple got out of a taxi together... He tried to say he had dementia. Guy was having non of it.
Then when we got inside they had staff patrolling the aisles looking for people talking to each other and telling them off like school kids.
It was a really tense atmosphere.
Then on the way out I heard staff say something to security about a gentleman with a stick.
I was waiting for my taxi and there was an Asian woman who went in. This guy was behind her. I'd seen no interaction between them.
He stopped the old fella and asked if they were together. He didn't seem to speak English and was confused.
The staff member gestured to this bewildered woman and said 'are tou with her?'
He said no
The fella came right up to his face (great social distancing) and said 'if I see you talk to her, or put anything in her trolley YOU. ARE. OUT'
Punctuating each word loudly like an angry dad.
The customer looked so upset.
I saw this with several Asian families but funnily enough he didn't stop to say the same thing to consecutive with people going in 
The whole thing just felt OTT and intimidating.
I won't be going back. I inface WAS there with a friend who brings me shopping because I have alMH problems and mild learning difficulties but I still like to get my own shopping. He didn't say anything to us. Even when he saw us packing up the taxi together.
I'm scared to go back now as people were being shouted at like school kids. One woman questioned back inside the shop if the security guard was the police as she had only asked a woman in the dairy section if she could see an item flavour for her as she left her glasses at home
