I think he meant that if the staff could speak English, the staff would not work at the Cantonese restrant because they can find better paid job, or the restraunt would pay them more if they can speak both english and chinese. I do not think you need tp pay more for you eating because you can speak english as a guest. is it clear now?
most of the Canton can speak both Mandarin and Cantones now. Even Hongkongnese, they learn Mandarin very fast. in church, The Cantoneses attend the Mandarin workship for the purpose of learning Mardarin. don't worry, you will see the situation soon, in which you walk in a restruan and only can be understood by speaking Mandarin. be patient. you can see. :eyebrows:
