Event of your choice.However, I don't go to scale modelling shows
Doesn't matter really, the characteristics are similar.
I was exhibiting a few years ago somewhere in Shropshire ... bloke comes up to me, badges, Bogsy type floppy hat (also with badges) camera, rucksack and BO. Starts chuntering on about some obscure details of a model that wasn't mine, then tells me about his journey to get to the exhibition by bus etc etc etc.
After a few minutes of being polite, I tell him that I'm on lunch and so hand over to my oppo and head off to the dining room. Throbber follows me still talking until I point out to him that I'm about to enter the ehibitors dining area and he can't come in. I leave him with "nice talking to you..." and close the door after me.
