So I work at a country club as a groundskeeper and work by myself most of the time and was told that I can’t wear one headphone in while I dig up weeds and dirt because it looks unprofessional

For reference its like 40-50k as the initial fee for members on top of a yearly dues as well and I'm paid $2 above minimum wage while I work to make millionaires have a fun day slapping a golf ball around, but its unprofessional for me to want to make work somewhat more enjoyable. Lovely
