Hello . Excuse me .   Yes . Can I help you ?   Do you remember me ? I just had lunch here a half hour ago .   Of course I remember you .   I think I lost my wallet here .   Oh , no . Really ? I didn't see anything .   Really ? You didn't find a wallet ?   No , I didn't . Would you like to go look by the table with me ?   Yes , I would . It's not here . And it's not on the floor.Has anyone sat at this table since we left ?   No . It's been empty the whole time .   Hmm . I don't know how it could have happened .   I remember , sir , that your friend took the bill.You didn't pay for the lunch yourself , did you ?   No . My friend did .   Then are you sure you took your wallet out of your pocket while you were here ?   No , I'm not sure . But I usually take out my wallet when I sit down.It ' s uncomfortable to sit on it . So I usually put it next to me on the table .   Maybe you lost it before you came here . Or maybe you left it at home .   I don't think it's at home . I think I had it when I left the house.But what should I do ?   Well , the first thing you should do is make sure it's not at home.Then , if it isn't , you need to call your credit card companies and cancel your cards . Next , you need to replace whatever you lost , your driver's license , things like that .   Should I call the police ?   You can if you want . But the police usually don't do anything about lost wallets .   Hmm . I'll go home and check . Maybe you're right . Maybe it's at home .   I'm sorry we couldn't find it , sir .   Thanks for your help .
