In my country (oz) there's been a general trend toward byo cups, mainly pushed through via a brand: keep cup [0]. To my knowledge it started several years ago in Melbourne and spread to the other cities. Many coffee shops these days have either keep cups, white labelled keep cups, or other style. Now that baristas are used to it, it's less of a hassle for them and is pretty much accepted in lots of places. In my area, maybe one in 5 customers bring their own... Many shops also give a discount for byo because their cost of a cup is gone. [0] https://au.keepcup.com/ https://au.keepcup.com/
