Person1: Good morning and welcome . How can I help you ?
Person2: Could you tell me something about safety deposit box rental , please ? I need somewhere safe to keep some insurance documents ; I just simply don't feel comfortable keeping them at home or in the office .
Person1: We have 3 different types of boxes . We usually rent for 1 year and the fee depends on the size and location of the box .
Person2: I think I'll go for the smallest , as it's just for documents . Will I be the only key holder ? I'd perhaps feel a little nervous if I knew someone else could have access to it at any time .
Person1: You can have more than 1 key if you'd like , but we must have signature cards for each box .
Person2: That's great ; I can give an extra key to my wife . I feel perfectly comfortable with her having a key . Thanks for your help .
Person1: If you have your ID and are willing to pay a year in advance , we can do that for you today , there is no need to wait .
Person2: OK , I'll take a small , for 1 year , in this branch , please .

Person1: So , Emily , how was your day ?
Person2: I don't think you really want to hear about it .
Person1: It can't have been that bad . Go on and tell me about it .
Person2: To be honest , it was horrible ! My manager is such a pain in the neck !
Person1: Why ? What happened ?
Person2: Well , he made quite a few mistakes on the monthly report and when his supervisor found them , my manager blamed them on me !
Person1: That's not very fair . What did you do ?
Person2: There wasn't really anything that I could do . There's always been a lot of bad blood between my manager and myself . If I had said anything , he would have fired me for sure .
Person1: Does he treat everyone in your department like this ?
Person2: He treats everyone pretty badly , but the way he treats me really takes the cake !
Person1: Do you have any idea why he treats you worse than the others ?
Person2: I really have no idea . All I know is that the thought of him really curls my hair !
Person1: Is there anyone else you can talk to about it at your company ?
Person2: Not really . I'm hoping to live with it for a while until I get a promotion .
Person1: That's very sensible . It sounds like you have a good head on your shoulders .
Person2: I try to be sensible about it , but it's not very easy . Sometimes you just have to grin and bear it .
Person1: That's so true . When you have a taste for success , you can't let dishonest people like your manager get in the way .
