Oh my goodness, thank you! so very much. That was really nice of you.
I had a great birthday, my son came home with my favorite pizza, which the only kind I will eat, a white pizza, with sliced tomatoes and spinach, I love it and it doesn't make me sick. Most foods do. And, a huge bag of M&M's, LOL, I love those, and then, a big can of Folgers, again my favorite and a wonderful funny card. It just made my day, oh, and then lottery birthday cards, and we won 4 bucks! I had a great BD. It was very nice, and my other son bought me a huge card which I hung on the china glass. And, then the girlfriends, and coworkers... horrible, people.

I always do off topic, on topic is boring.
It is not tipped that I know of. I was talking to the younger son and he said, he heard it squeaking for 3 years. The access panel is in his bedroom, it is a jet tub. He said, he heard/hears it squeaking when his brother is using it. I rarely, use this one, so this is all new to me.
I was wondering about tipping because I figure that is the worst that could happen. I am alittle, okay, maybe a lot gun shy of things.
Thank you for asking.
