I often hear these mistakes made by German speakers who are learning English.
They say: Where can I become a ticket?
Can I become a beer, please?
Remember, the verb to become in English is the same as ‘werden’ in German so the above sentences do not make sense.
Anyone who has learnt some German would probably understand what you want to say but to everyone else the sentences are just confusing.
Corrections:
Where can I buy / get a ticket?
Can I order / buy / have / get a beer, please?
Have fun learning English!
