バイト敬語

[The Lady Ashuko]

I'm in the process of applying for retail jobs where I can practice my Japanese out of class and while I'm fairly certain that the tourists won't care whether I use keigo or teineigo, I really just want to do things right. I've bought a book on keigo already, but what I want to know is what are the most important forms for a sales associate position so I can learn those first?

Here's what I have so far:
いらっしゃいませ
～ドル～セントになります。(but I can't remember what they said after they take the money! When they repeat back the amount you've given).
お待ったせしました

Any help you could provide would be wonderful. Mahalo!

[ryuubu]

Just a quick correction:
お待たせしました
