it's a conspiracy

The trouble with working at the good ole' Rohs Street Cafe during the summer is that it is ridiculously slow.  Not like our business is hopping all the time in the winter either, but a hot cup of coffee definitely has more of an appeal in the frigid month of January than it does in the steamy heat of July (plus we don't have air conditioning in the cafe).  Anyway, the slow business is almost torture for an extrovert such as me.  If I am by myself I like it to be because I chose to have alone time or am being productive (i.e. reading a book in the park, napping on my couch, etc.).  But sitting here with one or two customers dwindling in every hour is irritating beyond reason for me.  I would either us be busy (busy= one customer every ten minutes) or have us shut down so that I can be productive (productive= cleaning like a maniac).  I am not a person who appreciates in-between times.  I could write a whole blog on that psychologically loaded statement, but will refrain for the sake of brevity. 
It's almost like I'm on one of those gag TV shows.  I go to do something, and regardless of how long it takes, in walks a customer during the middle of it.  This especially occurs when I leave my station to use the bathroom.  Now using the bathroom when you are the only person behind the counter does get complicated.  You don't want to leave any customers waiting and you don't want to wet your pants...it's a delicate balance you see.  But it is almost an 85% probability that when I leave to use the bathroom, just as I'm getting situated, someone walks in the door!  This place could be empty for hours and the minute that I need to leave the counter....in walks a customer!  I'm pretty sure it's part of a conspiracy to drive me insane.  I think that there's a trigger on the bathroom door that signals someone parked across the street to get up and walk in at just the right time (or wrong time shall I say).  I don't understand this phenomenon.  If any of you fans out there have an explanation, feel free to educate me on the matter. 
Maybe I could solve the whole issue by leaving the counter more frequently...thereby triggering the customers and diffusing this whole twisted experiment.  I'll let you in on any further discoveries.
