Say I have a ticket I accidentally walked out with and forgot to cash can I go back in there and cash it?

Yes, I believe so, as long as it's within 30 days of the date it was printed.

It says how long you have on the ticket

Much more ease in your experience if you go back within the same 24 hours if at all possible.

Yes as long as it has not ben over 90 days I think

I'm sure you can

Yes u can it's better to go that same day
