Hotels have long had a tricky problem: guests with sticky fingers.
These travellers do not just lift free amenities such as shampoo,
body lotion and soap. Instead, they help themselves to ashtrays,
coat hangers and towels, especially those monogrammed with the
hotel's name. They also remove food and drinks from minibars and
later deny having consumed the items. Hotel analysts estimate that
the industry loses more than US$100 million a year from in-room theft
and replacement of worn items.
