You really can`t tell the difference by looking at them :-\ I was just wondering,it seems to me something should be different...I guess its a money thing.When I was younger and worked as a soda jerk at a Drive in Ice cream shop,We had a shake and a malt.The difference was what kind of a straw you put into the cup,a striped straw was a malt(boss was to cheap to buy malt flavoring) and a solid straw was a shake....people couldn`t tell the difference either just new one was better then the other....I think somebodys playing this game with me again....
