Are these Princess Cruises? I've spent quite a bit of time at quite a few bars on quite a few Princess ships, and have never seen a drink poured that was not measured. They are very clever, they will pour the jigger and keep pouring from the bottle. It looks good, BUT they poured the jigger before it was full and the "after" bottle pour is showmanship. You get neither a short, nor long pour. For me, it is all fun, we chat up the bartenders and servers. We take longer cruises, and tip a little extra weekly, not a bribe beforehand, just a nice gesture every week. The service, nor size of the pour changes after the tip, just the same consistent great service from day one.
