Would you use a coupon on the first date?

Scenario: You successfully ask a girl/boy that you have known for some time out on a date and are presented the option of using a coupon to pay their share. Would you do it? Why or why not? If yes, why? If not, when would it become acceptable to use a coupon on a date, if ever? How would you feel if the roles were reversed, and your date payed with a coupon? Bonus question: are there any other rules of dating etiquette that you object to? Examples: men should pay for food, men should drive, women wearing makeup, kissing on the first date, not using your cellphone while on the date, etc. Personally, I would never use a coupon on the first date. I'm not sure why, but the idea of using a coupon on a date is emasculating, and I believe it would weaken that first impression. I'd say after the fifth date or so I might feel comfortable using a coupon. However, I would be fine if my lady payed with a coupon on the first date. Discuss away!
