Please do not make this simple subject as crisis .Actually accounting team made a favor; Thai to English can be easily solved internally in your deparment or there is google translate .
Me and my team always obey the company regulations about mailing and also we try not to disturb management with unnecessary e-mails while receiving hundreds of e-mail daily
And the procedure of gift vouchers has already been discussed in one of our meeting
We only forward the request to you,the subject is not related with accounting department
Please contact with contract department cause the hotel is in Phuket you can talk or e-mail to Mr. Salim or Mr Arkin
I am sure they will help you
