My uncle's family ran a GradeA dairy for years and years, including using glass bottles and delivery every day except weekends, when they still had to milk, bottle and pasteurize the cow's output. I was kinda shocked when they got tired of all that and went to plastic jugs, and selling at the local grcoery stores instead of delivering in three counties. Folks said their milk was like drinking ice cream, it was so good.
It was a helluva lot of work, and barely paid the bills even then.
After I got out of the Army, I worked in a grocery store for awhile, and can still remember having to sort the glass pop bottles that came into the store. I was pretty happy when the glass bottles went away.
