No, that’s not very nice, and probably not allowed for him to visit you anyway, under the covid restrictions.
It might be warranted, if hamchang asked about extras.
As for the shop? It's been there for about 2 years and has a very good reputation. I reckon that if there was anything on offer, it'd be known by now, in a place like Cookham. I have friends near Cookham who use it - well, the females do. I did call in when I was in Cookham and it had a good vibe about it - for a massage. They were booked up that day but could have fitted me in for a half hour massage but that's pretty pointless, for a good massage, so I didn't bother. God knows when I'll next be in Cookham.
