Every time I go to a convenience store, shoe store, etc. the cashiers are always asking questions I have no idea what they are. Either they say it too softly and I don't hear, then they get scared when I ask them to repeat themselves, or they just switch to English and then I lose out in hearing the Japanese. I'm looking for something that gives a situation and then gives you the dialog that you should expect.
Also what is a good way to ask them to repeat themselves but in a louder voice since I can't hear very well? Whatever I'm saying results in a deer in the headlight stare that's getting to be annoying.
Thanks.
