I have to agree with the above post. Bev makers especially on the airbus just love to leak. The amount of times I've had to move like a ninja to avoid being soaked on landing at the back is unreal.
I find chillers a nightmare too. Especially on the 777/747. I know they're needed for food safety reasons etc but my god it makes the galley really REALLY cold!! Maybe they can temporarily turn off once they reach a certain temperature.
Having to open two doors just to open the door of s cart is also a hassle. This seems prominent on the airbus in the stowages towards door 2L.
I could go on forever but I think that will do for now!!!
