What's really annoying me recently is the fact that NHS staff are getting basically everything for free. Free coffee, free transport, free food etc. yet other 'key workers' are getting absolutely nothing.

I'd argue that supermarket workers are a heck of a lot more important than a lot of NHS staff, plus they come in contact with many more people who are potentially infected. 

I'm not trying to downplay the importance of NHS staff, but it all seems a bit unfair to me
