There’s probably at least one pair in every jacket and coat that I own, and every once in a while, my wife (jokingly) chews me out when she finds a pair of foam ear plugs floating in the washing machine; I sometimes forget to check pockets before throwing a shirt in the laundry hamper.
I’m long-time retired now, but for 27 years I worked in a plant where there were a lot of noisy, “ear protection required” areas, and because I was an industrial electrician, I worked all over the facility. So I got used to always carrying ear plugs in my shirt pocket. In the morning, if I was assigned a job in an area that I
knew was noisy, I could take my muffs (just like when we go shooting) and double up on my ear protection. But if I was just walking through a noisy area, I could just put in my foam ear plugs until I got to where I was headed. My wife found a
lot of foam ear plugs floating in the washing machine back in those days.
