I once came back to my parents' house after a session at Worcester Beer Festival. I had drunk quite a few pints of strong ale. When I came in, my father immediately reminded me to remove my shoes. I don't think he realised at the time how ingrained the practice of removing shoes was in me. I doubt that even in a drunken state I would forget to remove my shoes. Naturally, with the beer festival being held at a race course, he was worried about all the mud.
I suppose if somebody has only just got into the habit of removing shoes, getting drunk might cause them to lapse.
It's my job to alert people to the consequences of heavy drinking, so here is a good reason not to get drunk: You might forget to remove your shoes and bring all kinds of dirt onto your carpet.
