Hubby here again, sorry Novita, but you did not know that cash can be used for obtaining a visa.

This was the point of the question.

Thank you Pwb78 for confirming that you can use cash when using the meet n greet' service, to obtain visa. You are the only person to confirm this so far.

Thanks Winnie also, as Novita said, we have used this service before, but this was before they introduced the card only payment by passengers for visa on arrival. Now that Pwb78 has confirmed cash can be used, my friend will no doubt use them.
Again, good advice for anybody with family and friends arriving to use this service, it certainly speeds things along.
