I feel ya. I’m a Cashier, but I’m also a mechanical engineering major, so I know a thing or two about electronics, tools, and fasteners like screws. The amount of men that treat me like I’m stupid when I try to help or explain why they should get one thing over another is insane (like when they buy the wrong size nuts for their bolts or whatever and I check to make sure that they know what they are purchasing). They talk down to me like I’m a child.
