Burger King review: The 1 dollar milk shake

the cup is to small to hold a milk shake, so that it is to small to be supported by the standard cup holder designed for larger cups. To help make them fit napkins are used to increase the size of the cups to so the cup holder will support the cups. It does a poor job of doing so and the cups will very easily fall over spilling the milk shake out and if it is on the front seat of a care making a mess of the upholstery of the seat.
Also the cover of the shake will not contain the shake and more likely to spill out on to what surface is supporting the shake. These shakes a rip off as being to small in the first place.
