Want to hijack the thread and thumbs up to...
a) Brewdog - producing and distributing sanitizer - free of charge I believe
b) Polar - who charge a monthly fee for electric car recharge points. Waiving the fee right now and allowing emergency services to charge for free(small gesture I know, but doesn't need to be made)
c) Caledonian Sleeper - refund direct to my account for a cancelled ticket. They did this off their own bat. I didn't apply.
d) There's hundreds of apps and things going free at the moment now I think about it. Don't know if they are playing the long game here though.
