Of course you can say no. It still means Bob is an asshole. Bob, unlike you, has many more options. He deliberately chooses to take advantage of your lack of options, even though behaving like a normal, decent human being and helping you for free by simply giving you the goddamn extinguisher would entail no great cost to him.<p>People like Bob are not out there to help others. They&#x27;re out there to win.
