I seem to have started a bit of a discussion on this point, with nicebutdim and his sycophant DPG, but as you become more mature you find that trays are a convenient thing to use when you wish to eat in comfort in the living room watching the TV, the children have moved out and you do what you want rather than panda to your wants or your aspiration's for them.
Flippant or not my comment re "Kitchen Designers" being an oxymoron was a genuine comment, the design of a kitchen layout is one of the easiest things to do, if you can draw and work to scale, if that is too difficult for some then so be it, be in ore of those that can.
