On our first cruise, and our honeymoon we were on the Oceanic, and the ships were not as stable as they are now, and of course my husband was VERY Seasick! So after one of our dinners, I went off to the restroom and as I returned I noticed him running out of the room and then diving under the buffet table. He was getting sick and couldn't make it so he dived under there. The problem was when he had to crawl out and tell the waiters what had happened. I never told him I witnessed the entire thing until a year or two later.
Thank goodness for stablizers and sea bands now!!
