McDonald's receipts in Germany end with a link to a survey page.

Once you take the survey, you receive a coupon code for a free small beverage, redeemable within a month.

Lenny connected with a second phone and a laptop, then turned the laptop into a proxy server connected to both phones.

He opened the McDonald's app and entered a voucher code generated by David's programme.

The next step was ordering the food for a total of €17.
