Who knows if anyone's still looking at this thread, as it's been months since any new post, but I really had to comment on Reply #10. I don't know how to quote here, but the gist of it is someone nearby at a theatre had let loose with a "silent but deadly", and the poster "solved" this issue by pulling out a strongly scented lavender towelette, for which those in neighboring seats were thanking her. This brings to mind cautions by my choir directors and anyone else in charge of groups that must spend time in close proximity to one another: NO Perfumes, scented lotions, etc, as many people have allergies and cannot BREATHE around such things. Lavender is a huge problem for me, as I have both allergies and asthma, and thus if someone nearby me had anything "strongly scented" with lavender, I would be wheezing, coughing, choking, and otherwise miserable, to the point of possibly having to get up and leave the theatre myself, further disturbing those nearby who are attempting to enjoy the performance.
Strongly scented ANYTHING (perfumes, lotions, towelettes), should be avoided for the comfort/safety of others.
