If you believe that big companies are really doing anything for Covid then your having a laugh it's all just a smokescreen to look good. I've heard some rather damning reports about Morrisons from someone who works there in the sense of them bodging the number of staff who've caught the virus so they didn't have to shut the shop (this is in the middle of lockdown at the peak); deep cleaning the store and not actually doing anything at all after someone catching it and asking someone to come in 7 days after having the virus. This is from one of their largest stores in the North East (probably the biggest actually) so it's not some small secondary store they have.

Profits before safety any day of the week. It wouldn't surprise me if any of the big 3 are doing anything extra than what they should be doing normally (the Metro cleaning staff are actually doing something as usually it's questionable what they actually do) bar the occasional misting.

The fact that some are advertising that they're cleaning touch points daily now is quite disturbing - surely this should be done anyway...
