people need to learn how to say excuse me..

okay I hate when people dont say excuse me and just stand there waiting for you to move and then complains about it to the person their with about it.. 

to go into more detail yesterday I was at the thrift store and recently ive been looking for vintage dainty watches, so I was at the jewelry case and it was me, my mom, and my cousin so if someone else wanted to look they'd have to wait or be like excuse me can I look at this real quick or something of the sort you know?.. but instead this girl came up and at first she was looking at the glasses that was near the jewelry and she was looking at the watches I was trying on and then she walked away and as she was walking away she told her husband "I wanted to look at the watches but those girls were in the way" and then not even a full minute later she comes back with her mom and her mom gave me attitude saying "excuse me can we look at the watches you've been in the way this whole time." and I was like yea sure go ahead im already wrapping up here and then I just asked away from them. but what kinda ticked me off is its like babe you're 25 maybe even 28 acting like you can't say excuse me cause we were in your way and to add to that before she even fully walked away with her husband my mom and cousin left to go look at other stuff so at that point it was just me so I just found it weird she had her gown mom come up to me and just give me attitude just because she didn't want to say excuse me for me to move over and to keep in mind I wasn't even taking up all of the space either they both had more than enough room to both be looking at the jewelry. 

IDK THOUGH GUYS LMK IF IM JUST LIKE OVER REACTING OVER IT OR NO.
