It Doesn’t Hurt to Ask
Here’s a hack that’s borderline, if not blatantly, unethical. Say McDonald’s has come out with a new promotional drink. It looks good, but the $2 price tag is more than you’d like to spend. Here’s how you get unlimited refills (don’t blame us if this hack doesn’t work).
Get a normal drink at the normal cost. When you finish the drink, wait until the cashier forgets what you look like (you may need plastic surgery for this), then walk up to the cashier and ask for a refill. When they ask you what drink you had, tell them you had the promotional drink.
