Booking airline tickets

It's a fun and interesting experience.  All industries should work exactly the same way.

"I'd like a cheese burger please"
"That will be £1.20".
"But it was only 99p yesterday!"
"That was the weekend special price."
"Okay.  Here you go"
"Oh, there's also 21p VAT"
"Riiight...  any other hidden charges?"
"no.  By the way, please pay the £2.15 purchase fee"
"I see.  So that's not a hidden charge?"
"No.  It's simply an extra surcharge that you are obliged to pay for the burger."
"Okay.  What else will I have to pay?"
"Nothing at all.  So, what would you prefer - Beef burger or vegetarian?"
"beef please"
"Okay,  That will cost 45p on top"
"Oh.  I'll go for the vegetarian option"
"Good choice. Certainly.  That's only 60p"
"Right.  Do I get my burger now?"
"No.  You'll only be able to eat it between 20:00 and 21:00 though. Please check in at least half an hour early or you may forfeit your burger"
