Years ago waiting in the queue to board low cost airline flight, lady went through to check people's names matching on passports/IDs and their boarding passes to speed up boarding, me juggling with two bags, Duty Free bag and trying to take out my plastic ID from my wallet I put it in my mouth directly before handing it to her. She said "ewww it's disgusting!" - never ever did I put anything else like ID, card, keys nor cash in my mouth. Well, some people needs someone to make them realise that I guess.
My Royal Mail local delivery office changed opening hours during pandemic so many times, it is currently very generous with 8-13 every day, with until 1400 on Fri and Sat and additional second opening 16-20 on Thursdays. However, it is not a month ago when it was still 0600-0800 in the morning except Weds when it was closed. And for last few weeks calling cards I receive do not even mention opening hours, instead they strongly encourage to arrange redelivery.
Post Office had reduced hours but luckily they came back to full hours.
But for example Lidl was open until 2300 and they reduced it until 2000 in the beginning of the first lockdown, then put it up back to 2200 and that's how it stays till now.
This year I had a bit of a problem with Driving Licence, as the one I had was foreign, until I lost it and couldn't renew it in my country due to not living there anymore. Luckily I could make a new one in the UK regardless the fact that I lost my foreign licence. You can hardly find any information on how to do it online. I was trying to call them dozens of times on 3 different numbers I found and it was always rejecting the call. I then discovered online chat which was responding very quickly. When I finally managed to fill out papers correctly and sent them to DVLA and after waiting long weeks for them to send me back my new licence, I have received a Provisional one. I tried calling them again with no luck at all, so I used the chat again. They were unable to help me over the chat, they said I need to call them. So I explained it's impossible to get through as calls are immediately rejected every time I try, and I asked if they can call me back instead. That wasn't an option, I had to keep trying. Then out of nowhere, call went through. Once I was on the line, I didn't have to wait long, answered promptly and took my case into investigation. Two weeks later I had my licence exchanged into a Full one.
I think a good - quite opposite - example from the Railway is TfL Rail serving Hanwell station. Until first lockdown it had only half an hour service throughout entire day Monday - Saturday. No trains on Sundays.
In April they added half an hour service on Sundays between 9 am and 9 pm. Not long after that they added services in Peak time and it became 15 mins service in Peak.
Yesterday, for one day only, a Saturday, they made it every 15 mins for entire day.
