I was on a tour of a local attraction and one of the guides was sniffing every 10 seconds or so.
I was brought up to consider sniffing as rude and wasn't allowed to do it around my parents.
I found the sniffing to be unpleasant and distracting. I tried to ignore it but couldn't and after 10 minutes or so with no end in sight I asked them to stop. They said they had a medical condition ( I don't remember what ). I didn't say anything further - I didn't know what to say. They reduced the frequency and left soon afterwards.
Was the sniffer BU? WIBU to ask them to stop? What if they just had a cold? What if they had been farting or had tourettes?
