The work was done twice this way: in the evening Dmitry "washes", and in the morning I see a hairy and curved site!
I start writing and it turns out that he forgot to remove it.
The result: unpleasant attitude to you and your site!
The fact that your site brings you the money you pay for the services of the programmer - the programmer itself is not to pay. But money to get - they want everything. And the fact that your customers go on the site that has been spread across the sides - this Dmitry seems not worried at all!
