My new coffee cups work. Maybe I do want the 150ml version of these beakers instead of the 100ml. These were only a tenner, so I can give that a go.

Does this work though ¹?

C₈H₁₀N₄O₂

Hopefully that's the chemical formula for caffeine if it appears right.

Tenner on coffee cups is nothing, I lost twenty quid on cinema tickets earlier, trying to save some money. Wife wants T1 to go to see this version of Macbeth with David Tennant in. It was a proper play at the Donmar Warehouse, we're not going to that, but they're doing one night only at the cinema. I can get a discount on cinema tickets through work, by buying a voucher and then cashing it in on the cinema website. So did that, but it didn't work. And I can't get a refund because I opened the voucher. I have a support query in, I should get refunded, but I'm twenty quid down now and no cinema tickets.

Wife bought more tickets for Wicked on Sunday, I don't want to see that so I'm not going. But I paid so I'm thirty quid down there too.

Pay day in two weeks.

Estimated 2246 cups of coffee ☕️ from my espresso machine ² prob'ly comes to £0.96 a cup (including 3+ years supply of the actual coffee ☕️ beans and servicing ² but not the 'leccy).

Yep, it worked!
