Depending on what you mean, maybe. If you mean that your 30 seconds do not start until you have decided, you are wrong, but if you mean that you use the time it takes to arrive at your lie to decide that, obviously that is your prerogative unless that you take longer than reasonable to get to your lie because of it. But obviously, sometimes you cannot do these things before you see your exact lie, and then you in theory only have your 30 seconds to decide what to do and do it. In reality, I think you get a little leeway from your card mates, if you are in a tough spot. Especially if you are not taking excessive time on all other shots. But with a strict interpretation of the rules, you have 30 seconds to tap in from under the basket, to tee off or to throw from deep in a bush with no line out.
