Walter worked nights as a clerk in a fast-food store. On his last work shift, Walter's boss told him, "I'm really grateful for the year that you have worked here. I am going to give you a bonus of $1,000 in your last paycheck." When Walter got his last paycheck, there was no bonus. If Walter sues, the likely result will be:
A) Walter will win, as the promise is enforceable.
B) Walter will lose, as he gave no consideration.
C) Walter will lose unless the promise was in writing.
D) Walter will win, as no consideration is required to modify an employment contract.
