Multiple items with the same name

There are times when you have the exact same item in multiple menus/sub-menus but due to the limitation of no name duplication this is not possible.  

Scenario 1 - There are multiple bars located in a venue.  A Budweiser at the inside bar costs $4 plus tax (tax add), a Budweiser purchased at an outside bar costs $5 (tax inclusive).  These are the same items purchased from the vendor but are sold differently in the venue.  The Category would both be BEER but the Sub-Category would be different as they are on different menus with different tax strategies but still selling the same items in both bars.  Yes a simple name change may suffice but ideally the name would be the same given it is the same item.

Scenario 2 - Same as above except the same price and tax.  Site wants a "speed screen" type button as the outside bar only has a limited selection of items they sell and they don't want the staff to have to navigate the various menus to find the items.  Currently you have to rename the items to do this which then you have to add them together on the Sales Reports even though it is the exact same item.

Not allowing duplicate names makes sense to maintain a cleaner/smaller database but the limitations outweigh the advantages.
