"Would you like a drink with that?" asked the girl at the counter.
Drinks at the kiosk were just a dollar extra with the sandwich I'd purchased, but I declined. I explained to my lunch companion that I don't drink sugared softdrinks, juices or artificially flavoured drinks. And I can get water from a tap.
The same situation happens at the service station when I go inside to pay for petrol.
"Would you like to buy two chocolates for the price of one?"
Everywhere I go I am seemingly assaulted by food bargains. Cheap crap that I would not normally buy, but "it's a bargain" draws me in.
Fortunately, I've learned that it's only a bargain if you needed it, and "No" is not negative, it is assertive.
