One rather unexpected brand has been attracting attention with a creative effort...
Meanwhile, taxi app Uber saw the strikes as an opportunity to promote its service - although fellow cab firms Addison Lee and Gett had remained silent as of this morning.
Tube strike planned from 6pm today till 6pm Monday. Share your ride with uberPOOL to save on your fare and help keep London moving.— Uber UK (@UberUK) January 8, 2017
Cycling brands saw today as a good opportunity to promote the option of commuting on two wheels - and gym chain Fitness First has again attracted coverage and attention with its offer of free gym and shower use to Oyster Card-wielding Londoners.
Others, including W Communications boss Warren Johnson, didn't retain quite as sunny a disposition.
#TubeStrike thanks for the journey in and hundreds of wasted manhours, dickheads— Warren Johnson (@WarrenJohnson_) January 9, 2017
London may have a #TubeStrike today, but least we have our reasonable house prices, eh? [sound of weeping]— innocent drinks (@innocent) 9 January 2017
The day also provided a good excuse for pictures of cats, jokes, jokes involving cats and, among all this, even the occasional show of support for the striking workers.
Spare a thought for the tourists unable to get from Leicester Square to Covent Garden without the Piccadilly line ?? #TubeStrike— Rupert Monkhouse (@pert1993) January 9, 2017
I told the boss I'd be late in because of the #TubeStrike - she pointed out I live here. Damn.— Larry the Cat (@Number10cat) January 9, 2017
Finally, PRWeek can confirm that the Transport for London employee in charge of the Piccadilly Line Twitter account appears, so far, to be avoiding a repeat of December's meltdown.
