Ultimate Insult?

Expatguru, who blogs at Working in Saudi Arabia, offers some good advice for business visitors to the Kingdom. But somewhere in the middle he says:

While exchanging business cards, NEVER EVER keep your host’s business card on your hip pocket. It is considered as an ultimate insult.

Really? Do you, my fellow Saudis, consider it insulting for someone to put your business card in their hip pocket? I don’t know about you guys, but it seems to me that some people around here are easily offended.
