You were with Daniel at Walmart, both of you were on vacation in the United States after the racing season so you could spend some time as a couple and buy unnecessary things for the home. You approached Daniel with a coffee in your hand and a few items of clothing in some Hello Kitty print.
"Dan, love, will you buy it for me?" you looked at him with a smile "it's just that I paid for the coffee and..."
"You just offended me, love" Daniel put a hand to his heart in mock indignation "with me you don't have to pay for anything, remember the 3 rules: when we're together I'll pay for everything, you pay me with cuddles."
"Dan... that's weird, we never set rules" you laughed.
"And me, I pay for your Starbies" he pointed at you amused "besides, I hid your card this morning... that's what we're going to pay with."
and you both laughed at the joke and the silliness of the situation.
