Did you ever buy food from the snack stands near our hotel ?   Yes , several times .   How do you like them ?   Not bad .   I always have the temptation to eat something there .   Then , why didn't you do that ?   I don't know how much we can trust them . Do you have any ideas ?   Some of them , I think , are not good .   It doesn't taste good ?   No , I mean some of them are not clean enough .   That's my greatest concern . But how can you tell which one is clean ?   I judge by appearances .   I got it . I think it's worth trying .   It certainly is .   I'd like to try some kebab , roasted squid , and many different appealing things .   Don't try everything at one time , please .   I see . Thank you .
