Very Important Card handed out at Holiday Inn Ixtapa

It reads: Dear guest, This card is valid for one towel. This service operates between 9:00 and 21:00. This card is worth $250.00 pesos. When you check out, please return this card at the reception, in order to avoid being charged extra. And it is quite obvious: The customers do care for and do hand back their towels! (or their print work is really deficient)
