Straws

Straws aren't the most convenient things... They're all show and not very useful at all. Of course some are okay (Mc Donalds' straws for example, not too flashy), but the twirly ones with about a metre of straw all wound up like nobody's business that give you a headache because you have to suck too hard to get a deccent taste of whatever you're drinking, which in turn reduces your drinking experience.
