Where do you keep your speedy when you are at a restaurant and there is no extra chair to put your bag? Because the Speedy 30 is so wide that if you put it behind you it takes up half the chair. So do you keep it on your lap? Do you put it on the floor? My aunt bought these "purse hooks" to hook onto the edge of a table so that your purse can hang off a hook, but those hooks look kind of grannyish!
