Mobiles appeal to the science fiction geek in all of us. To this end, the makers of flip phones have missed a trick. Mobiles are at their best when being used for non-business stuff. They are a crucial tool for Dublin social life. Everyone is too disorganised to make meaningful plans in the evening, but you re all within walking distance of each other, so a quick call and you re sorted for beers and fizz.
Business cards are a bit more subtle, but they also have a secret life outside the office.
I've seen people unlock doors with them. Pick their teeth with them. Keep doors from locking closed behind them with them. Aside from these guerilla uses, business card etiquette is more settled. This respect extends to arranging meishi you have received at a meeting into a hierarchical pattern on the table in front of you, with the most important person's card at the top.
