The way this question is framed suggests you might be hitting the same wall most people hit with avoid.
Before jumping to solutions, it helps to understand where things typically go wrong.
**Most likely culprit:** a misunderstanding of the core requirement. This accounts for roughly 65% of cases I have seen.
**Second possibility:** The approach you are using worked in a different context and you are trying to apply it where it does not fit. tourist has specific conditions where it works well and conditions where it falls apart.
**Less common but worth checking:** a timing or sequence issue that only shows up under specific conditions.
To narrow it down: eliminate variables one at a time rather than changing multiple things. That will tell you which of these you are dealing with.
