First up, toothpaste tubes. They used to be made from metal, and you could fold the ends of them over as you used up the toothpaste, so that the remaining paste was kept at the nozzle end of the tube. These days, they're made from plastic, so once you've used more than half of the toothpaste, you have to constantly push the remainder up towards the end. However, it never stays there, it redistributes itself and you end up trying to mash the tube in order to get the blasted paste out. I hate these new tubes. I want the metal ones back, please!
Second up, the revolving doors at Morrison's Supermarket. Have they deliberately set these doors to revolving so slowly that you have the urge to smash them down, or is that just me? You always end up getting some impatient person (me) tutting and whining about them because they're impeding my progress to the Crabbies aisle, whilst someone else, who isn't paying attention, sets off the sensor at the back of the doors, stopping them altogether. Sometimes you get 25 people all trying to cram into the space at the same time, and at others you get a tailback because people don't want to stand in the space with anyone else. Why do they need revolving doors anyway? What's wrong with sliding doors like everywhere else?
