six foot rat snake inside my office

was skipping through my bathroom one day about to land in my office, when an inner voice yelled hey! Turn on the light first, which I had never done, but did it this time. Saw a six foot black rat snake, stopped my bare feet just in time. If I had landed on the snake, he would have no doubt taken a bite. Rat snakes are not poisonous but being bitten is not a delight. I have been bitten by a snake once before. I shuddered at having this creature in my house; shut the bathroom door. cost of snake-remover eradicating this creature is five hundred dollars. An exterminator came out, then we heard his hollers.
