Local pickup for speakers - should I let the buyer in the house or use the the garage?

Cash Payment for Sales are good if no Paper Trail is wanted, but are best avoided.

Bank Transfer is much less messy and can be checked for having cleared as fast as Counting Cash and checking for Fake Bank Notes.

Meeting a Buyer or a Seller face to face is a way to create a sale with Zero Troubles to follow, my experiences of meeting at Homes or away from the Home are with no incidents occurring that are wanted to be avoided in the future.

It is easy to lose a good customer and a bad customer by being over protective prior to a sale. The Plus Side, is that the bad customer will Toodle-Pip and probably break the communication with an unkindness sent, their type has this trait.

The good customer may continue the communication by being inquisitive about the reasoning for being protective in a way they are not familiar with.

The above are difficult to create when selling as a Vendor using a Service that has  a Buyer Protection, the Vendor has little to support them where Buyer Protection - Not Vendor Protection is the fundamental of the sale. 

There are other Options to consider, but they are not common practice as of yet but should become more frequently used for the good off all who are sellers/buyers wanting Fair-play to both parties.    

@larsman Between Two Friends why would one not accept cash.

Same as Friends will happily chink their glasses to the Toast Cheers to the point that the force is creating both drinks mix into each glass.

Trust is the Biggy, the individual (Buyer or Seller) when doing 'face to face' with unknown individuals,  has to shape their encounter to the point they have looked after their interest and welfare. 

If 'pindac' contacted about a sale item, there is an element of trust, simply due to the idea the name is quite familiar. If 'no forum history' or 'feedback history; contacted, the difference in trust between 'pindac' even though not known and the alternative 'no forum history' is vast and will be unsettling for quite a few individuals who have concern for their welfare.

Non Friends for the Seller - No Cash Reduces Risk - No Bogus Bills slipped into a Wad of Money!!! 

Non Friends for the Buyer - No Cash reduces Risk of Getting Robbed !!!

Non Friends for both Seller and Buyer - Bank Transfers are Instant - Monies are showing in accounts in seconds - A Transfer is as fast as counting the monies and feeling notes for texture and print fade.

Non Friends - Asks Females how Vigilant they are when in a Public Place where Drinks are part of the culture.

Individuals with an interest in self gain, have been spiking drinks with fatal potions and inebriant accelerants for Centuries.
