Passing in practice

Hi everyone...okay, for my first post I have an etiquette question...I just joined a Master's team a month ago, so I'm pretty new to all of this. My question is about passing people during practice. I know that theoretically, the standard procedure is to tap the person's feet to let them know you want to pass, and then they're supposed to stop and "pull over" at the next wall to let you get ahead. But do any of you actually do this a lot during practice? Do the people you pass let you do so without a problem, or do they get mad? Maybe this doesn't sound like a big deal at all and it seems silly that I'm concerned, but I haven't seen anyone even attempt to pass someone else during our practices, and so I'm afraid it would be rude. Plus, some people I swim with seem like they'd get offended, since they're pretty competitive. But last night, I was getting kind of frustrated because I was swimming behind someone who was slower than me, and I felt like I could go so much faster...is the appropriate thing to do to just suck it up and enjoy the "break", or attempt to pass?
