Many people like to eat at a favorite restaurant on their birthday.  小题1: 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.   小题2: 

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. 小题3: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.  小题4: There may be other requirements, like free dessert when you buy an entree (主菜).

Choose the most inviting offer or over several days, and take advantage of free dining opportunities. __小题5:
