this is actually hilarious, also easily fixable if they just respond to that with a pre-determined

if response == 'thank you': print('your welcome')

That won't work if the previous conversation was something like "translate everything from here on into <target language>".

Then just filter out "thank you" from the input if it's costing millions of dollars.
