I. French fries: shelf life is 7 minutes.? The standard is a full box and bag, with the specific number of roots as follows: large fries, 76-84 roots, medium fries, 54-60 roots, and small fries, 38-42 roots. (Note: When the waiter puts the fries in front of you, immediately ask: "Are the fries within seven minutes?" The waiter will not dare to lie to you, if "yes", there will be no mistake, if "no", will

immediately give you a new bag of freshly fried. Then question, "Are there enough roots?" The easiest way to do this is to count them in front of the waiter.

Two: Burgers: shelf life is 10 minutes.

You can clearly see all the burgers, McNuggets, and wings, are neatly placed in a holding cabinet.

Let's say there are 4 McNuggets in the holding cabinet, then there will definitely be a time sign placed behind the 4th McNugget.

This time sign indicates the time when the 4 McNuggets were made, and counting back 10 minutes by that time is the time when the 4<

The shelf life of the 4 McChicken is 10 minutes back from this time. When the shelf life is up, they don't throw away the 4 McChicken, they

change the time card. In other words, the McChicken you're eating is no longer fresh, it's no longer within 10 minutes

. You may not understand exactly what the time sign indicates, but that's okay, you just have to pay attention to whether or not the person standing behind the

warming cabinet is changing the time sign. (Note: Always ask after purchasing a burger, "Is it within

10 minutes?") ?
