I had a letter to post, but though my walk into town took me past this post box I didn't post my letter there.
If you look closely, you'll see that the next collection is at 9.00 a.m. "Sad/Sat" (Sadwrn/Saturday). But carrying on into town, there is a post box at the sorting office which has a last collection tonight (Friday) at 5.45 p.m. As my letter was fairly urgent, I carried on past this lovely old box to post it in the boring slot in the wall of the 1960s building that used to be the main Post Office, but is now a sorting office only.
Actually, to be strictly correct, it wasn't a letter, it was a printout of the accounts for 2018 for our local Quaker meeting, of which I am the treasurer. I'd emailed them to the Area Treasurer months ago, but for audit reasons he needs a verified copy signed by someone who has checked they are correct. I've been procrastinating on this, but ended up asking my elderly friend to do it yet again. I did try asking other people, but when you mention accounts and figures, a look of horror comes over their faces and they hastily decline.
