This is the wrong forum for the question.
Saudi Arabia inherits a lot of Bedouin culture.
Is it possible that in Bedouin culture, when you invite someone, you are expected to become the host to that someone?
It would be an embarrassment to Bedouin culture to invite someone, without providing that someone with shelter.
In Bedouin culture
- You should provide even your enemies with shelter, when shelter is needed. Therefore, providing accommodation to someone you invite is implied.
- To offer someone an invitation and have it rejected is an embarrassment. Therefore, to sweeten the "deal", you would provide every incentive possible so that your invitation is not rejected.
- Therefore, don't ever ask a Bedouin, or an inheritor of Bedouin culture, to "invite" you unless you are prepared to be intensely invited into their abode.
Etc, etc, etc.
