Yeah, only differences that I noticed other than being much quieter were:
- face coverings mandatory
- hand sinitisers everywhere
- pay by card in self checkouts in shops like WH Smith
- boarding into my flight (KLM) was done in zones
- I think Frankie and bennies (the one on theefy as soon as your pass Starbucks)was closed but Starbucks, Krispy Kreme and others were opened.
