Menards does not promote customer service at all! I have had a lot of people complain about the service they have received from Menard's employees.
In today's business world, the customer should be your main focus, and not whether they know what they want or what they are doing. Employees of Menards are there to help customers to determine their needs and wants and how to do things correctly. Not everybody is a "handyman" and Menards advertises that they can help the customer learn to complete projects on their own. Again, where is the customer service, leadership, and quality within the Menards environment.
As employees you can bash the customer all you want, but that is who supports the paycheck you receive.
When more customers go to Lowes because of the assistance they receive, the price they pay for satisfaction is going to be irrelevent. You job however, will be on the line because all employees won't be able to be supported by the lack of business Menards will have.
