dear sir/madam,

I am writing to you about the short stop of your trucks around my house on their way to the north.
when the trucks of your company have a short break on the streets around my house, the driver have left lót of garbage on the ground after their refreshment. when the trucks leave the place, the ground is covered with trash and a few minutes later there is smell and flies.
I would suggest that your company should tell your drivers to clear up all the trash on the ground before leaving.
I look forward to hearing from you and seeing good response from your company .

your faithfully,
Tran Vu Nhat.
