I'm embarrassed to be asking this but I get horribly self conscious and anxious when I don't know what to expect 
I'm staying in a Premier Inn at the moment (hospital placement student so I'm allowed!). They aren't doing food understandably because of Covid and what not but when I checked in they said feel free to order from Just eat or Deliveroo or similar.
How does this work? The main hotel doors are key card only, will they call me to come down and meet them at the door or buzz for reception?
I keep eyeing up the lovely online menus every night but I'm too embarrassed to order without knowing how it works! Can anyone help me?
(I promise I'm not usually so wet, I'm pretty confident in general!)
Thank you
