A few years back I worked for a small independent retailer that sold clothing and under garments (stockings, petticoats etc..) that seemed to appeal to a number of TIMs or perhaps the formerly known as TV. We ran into a few issues
They often took up a higher than usual amount of staff time either by phone or in person because of the in depth detail they wanted to go into discussing the clothing in relation to themselves. Some would venture further than that and conversations would take an uncomfortable turn with too much personal detail being revealed.
On one occasion a TIM (or maybe just a cross dresser- who can tell?) completely invaded my personal space by standing very close and attempting to engineer a conversation about how underwear feels on your skin under your clothes and what sort of underwear I preferred. This was my first real life #peaktrans moment as it was so clearly fetish driven and retail workers should not have to endure this. I think it would be very difficult now for any retail worker to object to this type of behaviour without being called a bigot.
They would quite frequently call and ask to visit out of hours, perhaps understandably, but this was totally vetoed as all the staff were female.
We only had the one singular changing cubicle so that wasn't really an issue and at that time a number would mail order anyway.
We also had a few issues with damaged clothing. Perhaps not a biggie in the grand scheme of things for a large chain but for a small retailer it is. Our blouses and dresses were just not designed for the broad frame of male bodied people trying them on. But of course in reality you cannot refuse anyone to try things on based on this. It is however just another small example of a female run business aimed at females being compromised by males. Similar to that bra company that was attacked on Twitter.
It's my experiences in retail of men who now fall under the TG umbrella that make me very concerned about self ID because the vast majority were very much not like our female customers in their behaviour.
