A friend travelled from the UK to Mexico recently for a genetic engineering
conference. The hotel refused all her credit cards, so the manager had to be
woken in the middle of the night to authorize some sort of sepcial
arrangement. The next day she found that the same thing had happened to all
the other Europeans - my bet is that someone, somewhere had written some
very "pragmatic" code.
