One male staff member responsible for reception was very irresponsible and extremely rude. When we arrived at the store to fill out the rental form, this staff member spoke quickly and did not explain item by item, only pointing out the required fields. When we double-checked with him to avoid mistakes, he was very impatient and deliberately mocked and ridiculed us. The first time he said one field needed the hotel name, and when I confirmed again, he shouted 'What is your name,' and I thought I misheard the first time, so I wrote down my name as he said. Then he accused me of not understanding anything, mocked us by saying 'yes yes yes in Thai,' and another staff member nearby just laughed at us, obviously ridiculing us for not understanding Thai. His attitude was consistently poor when we confirmed with him multiple times. I vacation in Thailand every year and have rented cars many times. I've never encountered such rude and uneducated service before. Later, when returning the car, the female staff member's attitude was relatively better.
