A plain damp room with many barrels of beer and wine.  The room is in need of a good cleaning as the floor is dirty and rats scurry about.
Storage room, Tavern
rat
his wife
I don't love my husband. I've been cheating on him with the stableboy. I would do it again, too.
Ugh...vermin.  I do not know why my love insists on meeting me here. Mayhaps you should have chosen a better husband? Silly rat.  Tis not my husband that is my love.  My husband is short, fat, bald, and lacks stamina.  No, tis the stableboy that I would do anything for. Hence the making a better choice? I did not choose my husband.  I was forced to marry him.   So I see.  You are going to want to leave rat.  When my love arrives, should he see you he will kill you.  He will not want you watching us. I would sort of say that maybe you should find a better place for such meetings, this is hardly a room that gets one in the mood. I couldn't agree more, but my love insists that this is the only place we will not be caught. I mean I am not even the only rat here, I suppose he is just used to the filth. He is a stableboy after all.   I suppose it is your life, do as you will.
