WaWa Door Etiquette

So... I stopped at the WaWa today for a pumpkin spice cappuccino...my new addiction... and I got into a door holding dilemma...one person coming in on my right and one coming in on my left...and my hands are full so I am using my back and my butt...are you picturing it?...so do I turn to my left for the person on my left  thereby blocking the person on my right or do I turn to my right thereby blocking the person on my left...oh yes an absolute dilemma...AND shouldn't they be holding the door for me since my hands are full...and should they hold it for each other...who goes first...who holds the door for who...does gender have anything to do with it?...how about age?...how about wait time...how long should you wait for the next person coming in before you let the door go...oh, THAT is a hard one...how about two people arriving at the same time...so many different scenarios and dilemmas...
