I have consulted with my job supervisor about import-export documents for customers. I think I should have the share information for specific customers about this and who contact with relevant department. I make the information poster for customer, when customer come into Lame Chabang Port Bureau. You can check import-export documents correct on the poster boards by youself. The poster as a medium of communication serves to transmit a message and can be mounted in any department that is relevant. The poster is beautiful, interesting, unlimit time for presenting information, and make for a memorable customer. The important the cost of doing a poster quite low compared other media. So the poster is the best choice.
