Can, May and Could

Dear Teachers,

"May I use this telephone, please?"

"Can I use this telephone, please?"

Is the use of "can" considered impolite?

Also in the fllowing case:

"Could you please lend me some money?"

"Can you please lend me some money?"

Is the use of "can" okay?

Thank you very much.

Best regards,

Zeyar

I would place the level of politeness as follows:

May I ... most polite; use only with a pope, or royalty, or high government officials, or in English class.
Could I ... "special" polite; can be used with anyone you don't know in public places such as restaurants, but it is not required. "Can I ..." will do as well in many cases. ("Could I ..." is for a more expensive resta
