Can you not vape then, cant say noticed. If you are sensible and just have a little go at HT / in toilets then never had an issue.
There is far worse smells than a safe cloud of vaper.
As for the numerous elderflower and strawberry comments. That is so 2014. It's all about the creamy flavours these days.
Let it go
There should be somewhere open for smokers and vapers to go at half time. They should not be allowed to do so in the stands or concourses.
