[speaker001:] Good evening, sir. What can I do for you?
[speaker002:] Bourbon, please.
[speaker001:] How would you like your Bourbon, straight or on the rock?
[speaker002:] With iced water, please.
[speaker001:] Here you are, sir. Bourbon with iced water.
[speaker002:] Thank you. Now how much do I owe you?
[speaker001:] The bourbon is 15 dollars plus 10 % service charge. So the total is 16.5 dollars.
[speaker002:] That is OK. Here is 20 dollars and you can keep the change.
[speaker001:] Thanks a lot.
