Please note that you must place the piano on the lot in order for this cash register
to function properly - the pianist must be able to access the piano (i.e. nothing blocking
her route through). If you do not do this you will likely find multiple versions of the
cashier NPC spawning all over your lot!

The Piano is included in the cash register zip as well as being available as a seperate download. 
Your Sims can use the piano as a regular piano at home.

As with all objects with NPC's place all .iff files in your usual objects folder
Place all cmx, skn and bmp files your gamedata/skins folder
