this made me chuckle, i visited a Spanish girl in a hotel, when i went up to the room and knocked no one answers, then 5 seconds later the linen closet in the corridor opened and a small spainish girl came out carrying armfuls of towels! she shoved half into my arms and said 'follow me'. funniest start to a punt.
then last year i visited an EE girl in a hotel, as i went along the corridor i noticed the linen closet was open, when i got into her room i said to her that they'd left it open, ' i'll be two minutes' she said and disappeared! 2 minutes later she came back in carrying armfuls of towels!
second funniest start to a punt!
so to answer the question, they help themselves to extra if they can!
