False assumptions

It's strange how your thoughts or assumptions usually come true. If you assume something or make a judgment about someone and then act how you would treat them if that assumption proved true it will typically come true. For example, one of my best friends and I went out to dinner last night at Olga's. We had Robert as our waiter. Two college/teenage girls walk in, (ourselves), and he assumes that we will not tip well because typically the younger clientèle does not tip very well at all. Well, by judging us so quickly and then treating us as if his judgment were right he self Prophesized his own future. By treating us like we would give him a mediocre tip he earned a mediocre tip. In the end we didn't want to be rude. Both of us are waitresses and we know their pain. So we gave about $3 for the two of us which was around 15%. He could have earned himself more, but by judging us so quickly and making false assumptions he did not earn it.
