I've never actually seen her eat tuna, but somehow she smells of it. I don't like to ponder on what orifice it's emitted from but I can confirm it is rather unpleasant.
Living with a smelly DP (as you may recall) I have a reasonably high tolerance for odours. However, this woman is in a client facing position and I fear her aquatic scent is a poor reflection on the business. (Not to mention her personal life.)
AIBU to want to tell her she smells of fish and this is a: bad for business and b: possibly the reason she never makes it to the second date?
OK so feelings may be hurt initially, but if I smelled like a John West warehouse, I'd want to bloody know.
