I'm not saying if Angelo should be complaining or not but this is what I saw.
Angelo is up and Belmonte is messing with the bottle to get a drink. Angelo hears a crinkle from the bottle and steps down and looks at Belmonte.
Belmonte puts the bottle down. Angelo steps up and Belmonte picks up the bottle again, this time by the cap with his left hand. While Angelo is on the approach you can see Belmonte grab the lower part of the bottle with his right hand. As Angelo starts his approach you can see Belmonte squeeze the bottle and you can hear the sound it makes.
I don't know if Belmonte squeezed the bottle on purpose to make a sound or if he was just squeezing the bottle to get a grip on it to unscrew the cap.
But unless he had no clue why Angelo stepped down the first time and looked at him , then Belmonte shouldn't have picked up the bottle and made noise with the bottle again while Angelo was bowling.
Belmonte's excuse about only holding the top and the bottle just popping is BS.. Either he wasn't conscious of what he was doing or he is an outright lier. His right hand was definitely on the bottle and you can see him squeeze it during Angelo's approach.
