No, not alcoholic drinks, dummy. In most cases.

Billy-
-You take a sip of his drink
-He blushes and starts stuttering
-"I-I could buy ano-other if you w-want!"
-You still just drink his
-He secretly thinks it's adorable
-"I don't mind just drinking this one, it costs less."
-"O-okay"
-Thinks of you every time he drinks that beverage from then on

Richie-
-He found a beer
-"Let's go try this thing!"
-Strategically makes sure he drinks first
-You take a sip
-"Did I taste nice?"
-You question him, and he oddly enough, goes shy
-"Did IT taste nice? I said it! Nothing about me or how I want to kiss you so bad all the time!"
-You giggle, kissing him on the cheek
-He spends the next fifteen minutes attempting to kiss or lick the spot on his cheek like a doof

Eddie-
-You barely drink any from his
-Acts disgusted, as he normally would feel that way
-Is confused on why he isn't
-Actually really wants a drink
-Oh no. You made him thirsty.
-He refuses to look you in the eye, but does take back his drink and drinks it
-You're surprised
-"Aww, he wants to taste you~"
-Trashmouth's name was changed to Smashmouth if you know what I mean. You literally split his lip with your elbow. Great job

Mike-
-Didn't seem to think much of it
-On the inside, was wayyyy overthinking it
-Is this an indirect kiss? Would (he/she/they) ever even like me? Ugh! It's probably just a friend thing for (he/her/them)! Or is it..?
-"You okay? You seem zoned."
-"Oh, yeah. I'm fine."
-You smile and go back to (drawing/writing/creating something IDK), leaving him to admire you.

Stan-(Imma have to headcannon this ramen boy, sorry. Gimme advice on this child. XD)
-"You know that's mine right?"
-"Yes I do, Stan, Stan the Jewish man."
-"Was that lowkey a Voltron reference? I DON'T EVEN THINK VOLTRON EXISTS YET!"
-"It does now."
"Dammit Y/N."
-Doesn't really care
-Kinda wants to kiss you now though
-No, really wants to kiss you now though
-"Y/N?"
-"Yeah?"
-And he gave you a quick kiss on the lips, smiling

Beverly-
-Takes a sip of yours
-"Not like you have cooties or anything... Right?"
-You go silent
-"RIGHT?!"
-Beaver never again takes a drink of your soda
-Your evil plot to keep maximum soda capacity worked

Ben-
-Suddenly even more shy than he usually is around you
-Considers it an indirect kiss, and can't stop staring at your lips
-"You okay, Benny Boy?"
-"Y-yeah, yeah! Great actually! Better than ever!"
-You go back to studying for a test, but he just stares.
-"Y/N?"
-"Yeah?"
-"Y-you're pretty/handsome.."

Henry-
-"That's mine you asshole!"
-Chases you down to get it back
-Tackles you, pinning you down to the ground
-Lowkey blushes, taking the drink from you
-Sees how actually helpless and somewhat sad you look
-"Just... Ask before you take my stuff, okay?"
-Rolls his eyes and smiles when you kiss his forehead, promising to ask from then on
