When my GS was about 4 y/o I met my DD and oldest GD for lunch one day. The restaurant was busy but not overly so. My GS kept asking for more tea and the waitress wasn't coming by to ask if we need anything else. He finally got tired of waiting and stood up on the seat (it was a bench), held his glass up and said in a very loud voice "more tea please". I was almost ROFL and my DD was ready to crawl under the table. I think everyone that heard him thought it was funny but my DD. Needless to say, he got more tea. BTW, he's 25 now, married and they are expecting their first child.
