nag 'n brag - You complain about something you paid for, you get a free it

You complain about something you paid for, you get a free item or a discount, and then you brag to everyone like you're a big shot.

I complained about my phone being broken, got a free upgrade, and now I say I'm the phone wizard.

I yelled at my delivery guy for being late, got my food free, and now I call myself the food god.

I raged about my gym membership, got a free month, and now I brag like I'm the gym king.
