Mon 160919 Went Post Office: dep./British Gas payment still too early

-(NOTE: This post is content recalled from 2 days back. Frankly, I can't remember everything; in fact, I can hardly remember anything?!)-

I went down to the Post Office to make a deposit into my bank a/c. I had to pay a bill urgently to British Gas...for the sum of  £77.03p.

However, when I came back in...to go and make the payment...after having given British Gas a phone call, first, just to check...I was told to NOT make the payment, yet; but, instead, to wait until the 19th of the month...which is another 3 days time...when the payment does actually become due.

What else I did with the rest of the day I honestly cannot now remember...? Did I go to visit a gallery? Did I go down the road to buy some 'fish and chips'...? I forgot. So, I'm just going to simply leave it at that.
