Personally we have always done this. Last night I enjoyed a long bath with a nice chilled glass of rose. Perfect.
However in laws are around and have just made huge catbum faces about dh taking his tea into the bathroom whilst he supervises kids bath. He's sitting on a chair with a magazine and tea literally just checking the small beings don't drown themselves, not exactly with his head down the toilet. Mil has just gone in to ask if he wanted her to take tea out again ( which he didn't)
I mean I wouldn't eat my roast dinner off the toilet seat, but in general is there that much wrong with food or drink in the bathroom? It's a perfectly clean bathroom that is cleaned basically daily and then scrubbed weekly by our cleaner. In fact it's probably cleaner than living room tbh as we don't deep clean that weekly.
Do you do this?
