Very similar to Glenn, we call them 3 P'ers, "Pick up", "Put down" and "Push off".
Then there are those who insist that "They LOVE wood" proceed to question you for 20 minutes, then walk away empty handed!
OR those who ask "Are they really made of wood?". Or after handling virtually every piece displayed say "They ARE wood!", and then say that there is nothing of interest!
After nearly 5 years of doing the rounds of local shows, craft shows etc. there is still nothing more irritating than those who spend many long minutes discussing every fine detail and comparing of prices, then insist LOUDLY that they can buy better, cheaper etc. etc. at their local shop!!!
You have got to laugh or you will be constantly crying.
