Because it is not AAFES. Not all franchises (such as fast food places, salons, etc) are contracted with AAFES and therefore can charge local state and city taxes. So no. Burger King is not doing anything illegal. A rule of thumb is if the business is inside a BX/PX they are AAFES contracted (not always but usually) but if they are free standing (like the BK at Scott) they are not AAFES contracted.
They do not charge taxes but I think the prices are different. I do not think that is illegal
