teaser push rules

Had a buddy last night claiming his teaser bet pushed one leg but he still got the payout on the others, which honestly sounded weird to me. I always thought if you push on any teaser leg, the whole thing either drops a line or just pays out less, but definitely doesn't get counted as a win. We were watching the last leg and it hit right on the number, so now we can't agree if that's the same as a loss or if it just kinda voids that leg out and you still collect.

Anyone else run into this? I'm not talking about straight parlays, just teasers specifically. Seems like every book handles it a bit different and nobody at my local spot can give me a straight answer. I’d hate to think I’m out here missing out on wins just cause I’m not double-checking the rules. There’s gotta be some consistency, right? At least with slot machines you know what to expect - even if it's just your wallet getting lighter.
