Help Request: Restaraunt

[MegaMasterX90875]

I'm still racking my brains trying to figure out how to make a decent Restaraunt script(s). I pretty much want it to when the player says "/buy food" or "/buy drink" it creates a little plate/cup NPC(s) in front of the player if the player is sitting in a chair. The food is $3 and the drink is $2. Food fully heals the player and drink only heals like 3 hearts.

Thanks in advance
