I'm a decorator. The wire and glue I took from the owner's house cost about 40 yuan. I don't agree to check my bag directly before the work is over. How to solve it?

You can talk to the supervisor, which is the decoration company. After all, they know the master's character. If you are looking for the decoration team by the direct owner, you can simply ask the owner why, but it depends on the owner's personality. After all, he paid you, and you have finished more than half of the work. Try not to offend, be gentle.
