Soy is my friend

Perhaps i am just being nit-picky, but after receiving the wrong coffee order on two separate occasions from DOME, i have decided it is time to cease visiting this particular chain.

I'm not being overly complicated! I just want soy. No cow milk for me.
I'm not one of those strange people i often encounter via my customer service job, the kind who seems to assume the counter-staff will just know the specifics of their order automatically. I try to be as clear as possible, so as to avoid inflicting all the usual psycho-retail-experiences i have encountered myself, upon the poor staff of whichever place i visit.

One soy mocha, one cappuccino.

Easy.

And yet, when i checked with the table staff who brought the order out, i find that no, i have not received my soy mocha, but a skim milk one instead.
I wasn't rude. I didn't cause a scene. I think my exact words to the increasingly jittery looking waitress were 'Well, then I probably shouldn't drink this' ...

J and i had already waited ten minutes for our first orders, and i had to wait another fifteen for my correct drink. J even went to the counter to find out if it was going to arrive. They hadn't even made it, or started making it until he asked.

I wanted to jump up and run to the counter (where all five of the staff were wiping glasses and gas-bagging) and exclaim "I'm not just doing this to be trendy! I really do NEED soy in my coffee!!!!", but by then i already wanted to leave.
