I've a friend that gets recognised, I won't use the word celeb as neither of us would use it to describe them. One day we had coffee, and the girl at Costa kept staring, she'd served us so could have checked their bank card to confirm if was or wasn't who she thought it was. Came over with a toastie that wasn't ours just to stare more. My friend put their hoodie hood up for a bit as got so fed up of it. On being recognised, they have said previously, if people ask and are polite then happy to take selfies and chat, but just gawping or being annoying to forcing a photo it irritates them. We were close to leaving due to this member of staff as kept at it for a good thirty minutes until we told her politely with the toastie we'd be up to the counter if needed anything.
