You’re there to serve. Knights of the round table used to kneel as an act of servitude to their master or to royalty. It was an outward sign of servitude toward another. [Don’t confuse this with slavery.] The act of serving another goes back to biblical times and is mentioned throughout literature as one of the greatest gifts to humanity. In retail right now, we often have employees acting as King or Queen, that they are doing the customer the favor.
