I am very unhappy with the after service, the technician clean out the grease trap. After he completed the job, I gave him the check then I went to check the kitchen where the grease trap is at. The floor is all messy with black mark everywhere, The sink, deep sink, the handle, and the hose are very dirty because of all Black smelly grease on it.
By the time I come out to talk to the technician about the mess, he was gone.
I used to be a technician myself, but for every job I took on, I always clean up the mess so it would look nice and clean just like before I came or better. That is hell all job should be done.
