So I popped my tire manualing down a curb and I went to patch it but I didn’t seem to have any glue left in my old tube of glue, so I went to the bike store and bought a new thing patch kit(cheaper to buy a new kit then a thing of glue) and I get home and go back to fixing my tire, I used the cap of the glue to pierce the top, I then tried to squeeze some glue out and heard a popping sound, I squeezed some more and there wasn’t any glue in the brand new tube of glue I had just bought and opened. Did the bike store rip me off? Or did I do something wrong?
You can get small tubes of glue the same size as is in a patch kit. Some stores sell them, some don't, but they should be cheaper than a whole patch kit. They're also available mail order -- you can get a whole pile of them cheap. You can also get a larger can as well. The small tubes are nice tho because, when opened, the glue dries up quickly. This can happen even when they're unopened, as you found out. The glue in the kit you bought likely had a defective tube and it dried up while sitting on the shelf. Hopefully the shop replaced it.
