I dropped a bunch of stuff at the charity shop I had cleaned out during the pandemic. I hot a coupon to use in the shop so went browsing and among other things got a cheap plastic beer pitcher with measurement lines, I had no intention of putting beverages in there. 😉 I was pleased to find that my morning piss was regularly about 1100ml and the regular empties were usually around 700ml, I have definitely seen better done but I was surprised to see myself on the larger bladder end of things.
