OFFERING

'Can I help you ?'
kita sering mendengar ucapan tersebut.
So, that is the example of offering.
The expression of “ Would you like....”is normally used for offering something to someone.
 
Sam : Would you like a cup of tea, Mr. Tom?
Mr. Tom : Yes, please. Thank you. Hmmm...this tea tastes good....and smells fragrant too.......
  Sam: Thank you. I’m glad you like it.

Ways to say it

Less formal expressions:
