Tried to fix a wobbly cafe table with a folded receipt. The waiter watched me for a full minute, then quietly slid a proper wedge under it. I tipped him the receipt.
Tried to park a friend's van outside the bakery this morning. It took four attempts and a guy in a flour apron waving me in like I was landing a plane. He gave me a free roll for the effort, so technically I got paid to be bad at it.
Tried the street noodle stall near the cart guy today. He asked if I wanted it spicy and I said yes before he finished the sentence. Regret was immediate and worth it.
