Do you currently, or have you ever had a job that required you to wear a uniform?

My first “real” job was at a movie theater where I was required to wear a white dress shirt, black slacks, and a black bowtie (not sure if that is really a uniform). Later, I worked at a McDonald’s where I had to wear my “monkey suit.” I hated that and was glad when they moved me to maintenance where I could wear my own clothing. For the last 24 years I’ve been wearing a US Postal uniform.
How about you? How do you feel about your uniform? Are you ever embarassed by it?
