If I was out for a meal with someone and they told me, for example in an Indian restaurant, they hate spicy hot food so they always get a korma/plate of rice/whatever and my different meal turned out to be very mild but tasty, I would probably tell them this and offer a little bit on their side plate or to dip a chip into the sauce. If they said they didn't fancy it I'd not push it.
On another thread someone's commented how tiresome and irritating it is to have people constantly trying to persuade them to try things they know they won't like.
Am I being an irritating twat offering a taste of things? I'm an ex fussy eater, I do have sensory issues about certain things (melted ice cream for example is always linked in my mind to dying cats and I can't even watch someone eating it!) so I'm relatively good, if I know what it is you can't handle, at knowing if x foodstuff will meet that category. I'd also never push it. But is it ok to ask?
