Sweden is actually sending a song in Swedish. This is wild. ๐Ÿ˜‚ #melfest #melodifestivalen #mello


The standing charge is an absolute joke. When our cheap fix ended, the standing charge had more than trebled over those two years. Clearly the standing charges are so the CEOs can afford their yachts. Itโ€™s a disgrace. #martinlewis


Anyone ever buy this coffee? Is it just me or is this the worst coffee in the universe? It tastes like a mix of dirt and vomit. I guess thereโ€™s a reason it was less than ยฃ1, but thatโ€™s no excuse.

At Starbucks ๐Ÿ‡ฌ๐Ÿ‡ง and not a tip jar in sight & excellent rapid service. Itโ€™s good to be back home a summer in The United โ€œif you donโ€™t give me at least 20% Iโ€™ll hate youโ€ States. ๐Ÿ‡บ๐Ÿ‡ธ


Just had the best idea ever. Private schools should be able to remain VAT free in exchange for them sitting the regular GCSE & A-Levels like the rest of society. If they want to stick with โ€œinternationalโ€ qualifications, then 20% VAT is fair. #edutwitter


Next time Iโ€™m delayed at the airport, Iโ€™ll think of this poor guy trapped at Leeds for 7 hours. Horrible experience!

Stuck at the stunning Leeds Bradford Airport for a lovely 7 (SEVEN) hour delay. @jet2tweets have generously provided ยฃ8 food allowance. A breakfast here is ยฃ16. More updates as events warrant.



Why does @foxrentcar / @TeamEuropcar_en have rules in the USA where you can only drive in the rented state and bordering state? I know itโ€™s in the fine print (that I didnโ€™t bother to read), but WHY is it there? Never heard of this rule anywhere else before!

How does this work? I need a rental car this summer. If I book with Thrifty, it will cost nearly $2300 (ยฃ1800). If I book with Gorentalcars.com, the total is ยฃ599. What's the catch? If I can save ยฃ1200, I'll do it, but am I setting myself up for disaster? @SimonCalder

AQA A-Level maths examiners? I was tutoring; solved this question the way my Edexcel textbook says (work out the probability the mean X being xbar); compare to the sig level, conclusion. AQA 2018 p 3 says to work out z values! My way not on MS. Is my way acceptable with AQA?

Does anyone know if I buy foreign currency with my @monzo card, does that count towards my ATM limit for the month, as Iโ€™m technically getting cash?
