Dude, come on, you have to be a fucking idiot way too credulous to take this at face value. It’s a picture of some guy calmly putting an acoustic guitar into the overhead compartment, and the Facebook post, with literally no evidence, warps it into how he started specifically “playing Maroon 5” and how he got shamed into stopping by some guy shouting at him to shut the fuck up. (You’d think they’d know the song he was playing for 30 seconds if they know it’s Maroon 5.) It’s the most generic “DAE Maroon 5 is obnoxious? XD” fake story you could make.
