Average espresso (oftentimes burnt) on the occasions I patronise the cafe.
Below is my experience today at the counter.
Me: Single espresso for here please.
DH barista: I can give you a single but I gotta charge you for a double.
Me: hah? why?
DH Barista: I only have the double espresso cup for the machine.
Me: no thanks. (and walked out)
There was no sorry. Most businesses I know offer the customer the upgraded product for equal price if the store can't provide what the customer requests, namely a single espresso. There were no apologies, staff who think they are too cool for you and upselling and it's not a bargain, 2,51$ + tax for a single shot, 20-30% more than neighbouring joints.
