If I regularly accompany my boyfriend to sporting goods stores, hardware stores and auto parts stores?

If I regularly (on every single weekend) accompany my boyfriend to sporting goods stores, hardware stores and auto parts stores without a single objection and stays at those stores with him for as long as he wishes (sometimes up to four hours), wouldn't it be fair that he should also learn to take me out clothes shopping without complaints, especially if I am spending my own money and not touching a cent of his? All I ask for is a little bit of his time, is that too much?
