Little backstory - I work for a very popular ferry company in the UK that travels Dover - Calais and on my journey to work I have to wear a hi-vis that has my company logo on it, and a lanyard with my picture and company name on. I heavily rely on trains to get me to and from work (I know I live on public transport!)
So I’m at the train station chatting to ex colleagues from my previous job when this stuck-up man approaches me (we will call him SUM, for short)
SUM - “Where are the toilets?”
Me - “I don’t know I don’t work for the trains”
SUM looks me up and down
SUM - “I can see, that now where are the toilets?”
ME - “I still don’t work here I don’t know”
SUM - “Yes you do work here! You work on the platform!”
ME - “I really don’t, I work for (insert ferry company name)”
SUM - “Then why are you wearing the stations uniform?”
ME - “Huh? My uniform has (ferry company name) printed all over it”
SUM looks me up and down again in disgust
SUM - “Whatever lie to me if you must!”
He then walks off and proceeds to ask actual train staff in completely different uniform.
tl;dr - Man assumes because I’m wearing a hi-vis vest that I work for the trains even after inspecting my uniform and refuses to believe me.
