in the booth pushing buttons behind a screen? or out on the forecourt filling up the cars?
[Edit for clarity: Wearing a face mask]. That will be next to useless with a face full of fuzz - i wish your customers good luck......
Yes, "pushing the buttons" as you put it, and yes, behind a nice perspex screen while taking payments. But that is only the one half of it really.
Shelves to stock, forecourt bins [full of disposed, disposable gloves, and other detritus] to empty, etc., and mostly very nice responsible patrons. Though there are some I would describe less charitably ...
As for face mask wearing, I have some decent quality masks now, that fit well. I does not take genius level ability to fit a mask properly. In spite of the barber thing, I remain clean shaven, a skill I learned a very long time ago when the order of the day was razor blades in a razor with two closing clasps on top operated via a screw turn at the end of the handle.
Strangely, I converted to disposables years ago when my luggage landed in Budapest, while I was flying to Oslo! It only took three days for me to collect my suitcase from Moss railway station in the Ostfold [Norway], but by then I was used to the emergency disposable overnight bag SAS gave me along with profuse apologies for the luggage mistake. I wonder if that level service would be the norm today. Not with Easyjet, I suspect.
Anyway these days I shave with soapy lather and BIC disposables. Cheap and cheerful!
