Good morning , sir , can I help you ?   Yes , I was wondering if you had the time to show me around this exhibition ?   I'd be glad to , sir . But may I ask what line of business you are in ?   I'm in the electrical appliances .   I see . Would you be interested in seeing the audio-visual products ? They are made by our company .   Thanks , they are rather attractive . But I think there is nothing better than seeing things In actual operation .   Yes , of course . Would you like to make an inspection tour of some factories ?   Yes , very much , if it wouldn't add inconvenience to you . First hand information is always more valuable than reading pamphlets .   I'll make the arrangement and let you know the time tomorrow .   That would be great .
