Having been a station supervisor in my previous TOC and a Guard at my current one, I have and do refuse people travel for being drunk. Both TOCs also hire agency security guards weekends and evenings to control anti social behaviour. So I’m not sure where your getting the impression that it’s only MerseyRail.
Merseyrail are undoubtedly much, much stricter on what they class as unfit than any other TOC.
