You know they like you by the way they yell at you
The gentleman in the middle is the innkeeper in Jandvik, which is in Suramar, of all places. When you engage him to purchase items, he greets you with such cheerful epithets as “I spit on you!” or “Sniveling pig!”. And when you’re done, he send you on your way with a jaunty “And don’t come back!” or a simple “Begone!”
I’m sure this is considered the pinnacle of manners in Valarjar society.
