BT! I just read your thread here, and I'm glad you accepted the job. You may even find you really like it! As for your "image" and what girls think...What woman worth knowing would dismiss you based upon your job?!!! Any good female friend should congratulate you on working at a good-paying job of honest work!
I'm a teacher, and I often envy the janitors at our school. They don't have to deal with the chaos and problems of behavior from students! In that respect, I would enjoy the peace of the work you are doing!
Love
Patty
