1. Do not steal the hotel bathrobes
It’s ok to take the complimentary soap with you, or even the tiny bottle of lotion. What is not ok is to take pricier items, like bathrobes, with you. Bathrobes go from guest to guest, so you are not supposed to take your home with you.
In fact, if you do so, you might be charged for it. Save yourself the embarrassment, and if you want to take something with you, stick with the tiny vanity products.
