"But it's also about the community - if you see someone at the supermarket or the chemist,talk to them. Offer them some support.
"Don't assume they're not abiding by social distancing,they just might not be able to."
Mr Cleaver said he had received reports from some clients who had the toilet paper in their trolleys taken by someone and they don't notice until they get to the check-out,and others who had people cut in front of them in queues without realising.
"This crisis is bringing out the best in people,but the worst as well,"he said.

Scott Grimley,who is blind,said that his shopping trips had become exponentially harder in the past few weeks.
"We quite often can't work out depth - so it gets tricky for us to practice social distancing so we have to use things like passive wayfinding[using smells,the feel of the ground etc],"Mr Grimley said.
"When you get to the shops and you can't find the product,you're not quite sure what's going on."
Mr Grimley said he was lucky that he had a partner who made shopping easier when they went together,but on his own,it was a struggle - he said he even walked into a table that one store had set up in front of a register.
Another time,he couldn't see a sign saying that customers had to pack their own bags,and stood at the register for minutes before someone told him.
"Supermarket staff are very helpful but they're not always available. It's a challenge to get down to the shops ... it's a whole planning sequence for us,"he said.
Mr Grimley was diagnosed with retinitis pigmentosa as a 12-year-old,and declared blind at 28.
"I tried to bluff my way through it for a few years,using what sight I had left,"Mr Grimley said.
In 2018 he got his first guide dog,Dudley,and they've been"inseparable"ever since.

"He's a bit confused sometimes when he's supposed to stop a bit farther away than he's used to,"he said.
He said that those with vision impairments were trying to look after families and loved ones like everyone else,but just needed a bit of help.
"If you see someone with a guide dog or a white cane,reach out,let us know what we need to do,"he said."I think the main thing to is that when it comes to helping us - being open and aware is great but don't try and pat any of the dogs,look them in the eyes or speak to them."
"Just being respectful really helps us."
