Coffee?

I am very fussy about what I put into my mouth (hahaah and no thats not meant to be rude) so when it comes to the perfect cup of coffee I am still on a mission. I dont actually drink hot coffee, only chilled lattes but lately I am getting really pissed of at people (staff) who can't make what I order.

An 'iced Hazlenut latte on skim' should translate into 'she wants a cold drink' but instead the morons at mc cafe have 3 times now made me the wrong drink. I am going to lodge a formal complaint very soon. Stupid blog about coffee I know but Im mad at the dumbness of some workers.
