Gross. I had bubble tea exactly once while interviewing at FB. I had to choke it back and try not look like an idiot.
Pretty sure that is the one and only reason why I didn't get an offer - "this dude is clearly from the Midwest and has no place here." /s
Jumping from "I didn't enjoy bubble tea" directly to "so they probably hate me because of their elitist socio-demographic biases" comes off as self-pitying, and pretty highly unrealistic.
