What Annoys you? (Research)

The fact it's impossible to get a drink of water on the move in the UK without resorting to plastic bottles (and basically what @pastry_bot said, the much wider issue). Not sure there's a design solution to this though because water fountains already exist, there just seems to be a national conspiracy to support the bottled water industry. I have noticed that water fountains are much more common in the U.S.
