My pervious local store had to allow seats back a few years ago because of the aging population of the gamers
oh and the guy who was in a wheel chair
. When they moved from their old location to new they got the guys who installed it to make 2 tables that could be height adjustable so he could play. This also helped for the younger kids who were playing as well, as previously they had to stand on footstalls and stuff. Also meant that because of the smooth mechanism that raised and lowered the table you could adjust the table down for nice photos on your cam-phones that you didn't have to hold your arm high in the air to get a good shot of the whole field.
