<human>: Could you distill the essence of the text into 1-3 sentences?

I work in retail and my store, like many others, is judged on our conversion rate.  For those who do not know, conversion is the number of transactions vs. the number of people who walk in.  It is expressed as a percentage that is reported to our corporate office and for which we are held accountable.  Our store, and again MANY others, has a small white box attached to the ceiling right behind the door.  Each time someone or something passes under the box (through the door), it ticks and counts it as a person.  This thing is indiscriminate in who/what it counts; kids, dogs, strollers, the delivery man all count. One of the most frustrating things is when someone stands under the counter as it continues to tick, or if they keep walking back and forth from one side of the store to the other.  There are several other irritating scenarios I could describe and while I do not expect most people to know or care, it is something that we are responsible for and is a main reason for the sales people trying so hard to sell you something, ANYTHING.  It's because our bosses know you walked in and they expect us to convert you from a looker to a buyer.  So please, be considerate to that fact and try to make as few trips as possible through the door.
<bot>: You are counted every time you pass through/near the door of most retail stores.  I am responsible for getting a certain number of those counted people to buy something.  Please don't fuck around under the counter.
