When you are trying to communicate with your guests, it's great that you want to help your foreign guests feel at home by using English. However if you put the wrong words out there, it sticks out to your foreign guests and can do more harm to your brand image than it does good.
For example here are a couple of pictures;
This picture asks us to eat 'quiently' unfortunately 'quiently' is not a word. 'Quietly' is likely the target. Now, your foreign guests are having a chuckle and the importance of your message is diminished.
This water be good to drink. 'Be'? I have some elementary school students that can see the mistake, 'is' would be correct. The grammatical error may not stop people from drinking the water, but it, again, affects your brand.
It's easy to avoid such mistakes by checking your English beforehand. If you use our sign checking service, it will not only be done at a reasonable cost, but we can offer some more suggestions that might add a more authentic, native voice to your signs. For instance the first sign could be, "Please respect other guests and refrain from making loud noises." The second sign could be, " It is safe to drink this water, please enjoy!".
Let us know if we can help you.
