In fact, McDonald's provides places for diners to squeeze ketchup, but we haven't found that McDonald's and KFC belong to the category of fast food. People choose it not only because it is delicious, but also because it is fast and convenient, so McDonald's didn't specifically point it out. When I didn't know it before, I squeezed it on the paper or napkin on the plate. It is very unsanitary to wet the paper with ketchup every time. But now we know that the three of them can squeeze ketchup, which is very convenient and hygienic.

Fold down the protruding part of the French fries box and you can squeeze the ketchup. Ketchup is usually eaten with French fries, and of course it should be squeezed in the nearest place to the French fries. There is usually a piece protruding from the back of the French fries box. Originally, it was to prevent too many chips from falling off, but this protruding piece can just be folded off, squeezed with ketchup, and eaten while walking. This method is very suitable for ordering French fries as a snack.

The lid of coke can squeeze ketchup just right. Most people will choose a set meal when eating fast food, because the price of the set meal is reasonable, the collocation is very rich, basically contains what you want, and the set meal collocation is diversified, so you can choose freely. No one can refuse the coke in the set meal. Even if you don't order a set meal, you usually order coke. The coke of McDonald's is Coca Cola. McDonald's generally choose paper cups and plastic lids. This lid is just right for ketchup. Just take the lid off, put it on and squeeze the ketchup on it.

Squeeze it directly into the greasy paper of the hamburger, or squeeze it into the hamburger to eat. The oiled paper wrapped in hamburgers is oil-proof and waterproof, so you don't have to worry that ketchup will wet the oiled paper, and the oiled paper itself is used to wrap food, which is very hygienic and safe. If you like ketchup, you can ask the waiter to take more ketchup when you take the meal and squeeze it directly into the hamburger. It's also delicious. Even if you don't order French fries, you can ask the waiter for ketchup or other favorite sauces.
