Saw this on Burpple & thought the concept is interesting & different. Decided to give it a shot; there was a 1-for-1 offer anyway, if you like their Facebook/Instagram & quote milkshop & burpple, or something or another... But the guy at the counter didn't seem interested to hear me out.

Nonetheless, I got my drinks at the promotional price, but I could do with a little less grumpy/disinterested of an attitude.....
