I was told I must take a Rite Aid purchased drug test in my boss' office after work or be terminated.

I volunteered to take a medical, or professional test, but thought that this was inappropriate and very unprofessional. The company also has no drug test policy in place, so I'm not sure they can legally require a targeted test anyway. I was told that they would schedule a medical test in an Dr.'s office. At the end of the day, I was then told because she couldn't get it scheduled in a Dr.'s office, that I must submit to the home kit there or be let go. I re-fused for multiple reasons. 1st my boss is female I am male, and didn't think she should be administering the test in her office after work 2nd there is no testing policy in place. 3rd I believe I was targeted for my appearance (tatoos). because I refused I was terminated
