Both of those are offences. For the first you will get a PCN. For the second the shop will be heavily fined.Lots of things that are rightly separated by certain characteristics are open to abuse, from parking in disabled spaces to getting alcohol when you're under 18.
These are both legal requirements. There is no legal requirement to be a biological woman to use a woman's toilet, nor has there ever been. Further there is no way to police it. Your obsession is pointless.
