I’m away for a few days in London with DD (19yo). We both have separate rooms in the hotel. DD vapes (she never smoked before vaping so she’s one of those who just took up vaping unfortunately), I tried to get her to stop when she first started vaping last year but I couldn’t so I’ve just come to accept now that she vapes and that there’s nothing I can do about it. Whilst in London, DD has been telling me that she’s been vaping in her hotel room even though the hotel says vaping isn’t allowed in the rooms. I’ve told DD off this morning for vaping inside her room but DD says I’m being unreasonable to tell her off for it because there is no one else in her room besides her so she says it’s not affecting anyone else or causing any problems so she thinks it’s fine, I also told her that the smell will linger probably but she’s insisting that the smell will be gone before the next people check in to her room, she also says that she has vaped in hotel rooms before apparently without issue. AIBU to tell DD off for vaping inside her hotel room?
