I only pay when I want to. We always discuss the bill before we even start eating. It's not a big deal at all. If I decide I don't wanna pay for whatever reason, then we'd discuss it before even going out. Don't be immature and insecure about money and only tiptoe around discussing it when the bill is there, doing silliness like whistling when it comes and going to the loo leaving the persona t the table or pretending to want to pay for it? Just calmly say, "who's paying?" or "I'll pay for my meal." If you say that you better have the money just in case they take the offer though! The whole "going dutch" splitting in half thing is STUPID and pseudo-mature. Like "let's not discuss **** this let's just do math right here and divide £142.63 by 2 for the both of us." Smh.
If you can't even decide on who pays for the chips I mean split up fast.
