Costa coffee "comfort zone"

After a frustrating afternoon in our local shopping centre in Stirling looking for slippers (yes hospital looms) I needed to retreat to a “comfort zone”.
 
So it was a quick trip to Costa coffee.
 
Finally, I did find a pair in the fourth shop. It appears slippers are a Christmas buy. Strange as it may seem I do not possess a pair of slippers, until today, because in the house I never wear anything on my feet
