This happen to me on different tiles and on rich also .
- first this is acting rich exemplifies being rich .(this may be so if you entertained the idea that rich people can spend whenever and wherever they want, or you read law of attraction books about acting as if “physicalise”
- the subconscious believe that is rich or soon will be rich and acting that way .
- the way you write your question appear that you see this as a negative thing. If that so maybe you should pay attention to your feeling after paying ( resentment,angry, curious, trusting, hopeful,etc ) if the situation (spending money is wrong) is healed you will feel neutral or normal .
