Supersize McDonalds? no need. Follow the Ronnie guide to prodessional whinging:
Buy your McMeal thing. Take a huge bit out of the burger, a hand full of fries and a large gulp of the drink, then return to the server to complain that the burger is too cold or something. Insist on a replacement meal and enjoy another full one.
Also, in shops imply that you are from head office. YOUR head office of course, but they will assume theirs. gets great response.
Another one is to wait until they finish and then say...' Do you remember in your training, they talked about MYSTERY SHOPPERS? Yes, well you have just been serving one. I'll pop my report in the post.
WHINGE, COMPLAIN and demand a refund or free holiday.
I have had free flights, a free holiday, free meals, two free tyres from Vauxhall, Free upgrades on flights, free taxi rides. WHINGE your way to a better life.
