First of all...we a very glad your friend like the site and we hope you will do the same.
For me your story call out fake...
Since you state that you are in your shop, I wonder if he is trying to take your attention when other do a little shop lifting.
I find it very hard to believe that a "good tarot reader" will behave like this....yea I find it direct not thinkable.
If a sound reader have seen any "danger" for you...they would have said so....because that will give him much more peace then if he say "pay me 50 dollars
and I shall tell you about something bad that you can avoid"....if you then say no....he will carry the guilt the rest of his life....and that is no amount worth.
Another thing is that none real Reader would have offered their service that way.....so this is fake....or trying to outsmart you.
Always have in mind that any reading are an indication about "What" can happen in the future if you follow the same path. Since we each day take different decisions we change our part all the time. So all bad readings are in my opinion "of little use"....good Readings that can put you on the right path is on the other hand good....because you as person must then choose to follow that path that gives the readings outcome.
So don't have any fear...and next time anyone come into your shop and start to give readings...ask them to leave...they are not worth listen too
Good luck
