Many people like to eat at a favorite restaurant on their birthday.   71  Here are the tips about how to eat for free on your birthday.

Notice promotional (促销的) cards or signs at restaurants for their e-club or online notification of special offers. Sometimes it is called a birthday club. In some cases they ask for your email address and at other times, you register online from your own computer.   72 

If you don’t know whether your favorite restaurant has an e-club, look them up online. Just search their name if it’s a chain. Look over the webpage for anything that says SIGN UP or JOIN. It may call it an e-club.

You will receive e-mail advertisements from them.   73  if it asks for birthday and anniversary dates when you sign up, then the restaurant usually will send you a personal coupon and invitation for that event.

Check your e-mail the week leading up to your birthday. All the e-clubs that you signed up for will be sending their invitations.

Read the fine print on all the offers before deciding where to eat on your birthday. Some are only on the exact date.   74  There may be other requirements, like free dessert when you buy an entree (主菜).

Choose the most inviting offer or over several days, take advantage of free dining opportunities. __75 

A.Anyway, look around for these offers and get signed up.

B.However, others may be for any time over a two-week period.

C.But how can we eat better in a free restaurant?

D.It would be an even greater treat if the meal or part of the meal were free.E.      Why not celebrate your birthday for a whole week, not just one day?

F.      Often the advertisements will include discount coupons(优惠券).

G.     So don’t go to such restaurant.
