Euston has the traditional type, and it's still common for them to do

Yes and no. When First took over the GN side, they were checking on
peak trains and catching lots of people - especially people who
assumed the RPIs wouldn't squeeze through busy carriages. Once they
started to man stations, it seems the message got through. Now when
they grip on busy trains, almost everyone as a ticket. In fact, the
only real issue is people sitting in first class on trains that aren't
declassified.
