Me and my friend went on vacation together and we shared a suitcase. She insisted I take some of my stuff out to lower the weight so we wouldn't have to pay any extra fees, fair enough. Until I find out when I do the maths that even though I only took 1kg of stuff in the suitcase she took 4kg. She even took out my beach towel saying we could just borrow hotel ones and I then find she has a small towel herself and a facial towel. This just really pissed me off as I planned and booked the entire holiday and it was my suitcase we were using as well.
