"I see your [bet] and raise you [x]" - would that be accepted?
Saying call and then adding a raise is similar to string betting, where you first put some chips to gauge your opponents reaction, and then put in some more. That's not allowed but so many beginners do it.
Some places may let you do it once, but by rule its not allowed in Casinos.
Dealers tend to just shut down anyone that plays silly games around delaying or feinting what they're going to maybe do to. I was at Acapulco Joe's one time playing the cheap limit tables with a dealer that was out of patience with this one guy that was acting like he was on national tv for the world series finals. Finally at one point when he was dickering around she just looked at him, said "he calls" took his chips and moved on lol.
