"How can I help you?" Which is what more companies should be saying to each of their customers.
Depends on how many customers to which you are referring. If there were one angry customer in front of me, I would say, "This customer's head looks as if it were about to explode." If there were an entire mob I would say, "These customers' emotions are running quite high as they feel they waited in line for nothing."
You tell the customer nicely to please stop yelling and use an indoor voice.
Sorry would you like to reorder.
In Kannada, we would say: Giraki or Kolluvava.
I would tell them to go see one.
A sample of a conversation between sales and a customer would start with sales asking "May I help you?". The customer would then say what they are looking for, and the sales person would explain what they have to offer.
Cliente - noun, both masculine and feminine
I prefer to say: The customer is not always right; but, the customer will always be happy.
I would say u purchased it
"Buy it, please. It's rather good."
I would say about twelve dollars.
Say to the customer, "Sorry, we can't sell this to you without proper identification, but if you were to come back at a later time with the proper documentation we would be happy to serve you."
