I have had a maximum of about 5 Asian custy's on my round at any one time:-
1. Poor payer, eventually dropped
2. Poor payer, dropped, begged me to take her back which I did on condition she signed a monthly standing order. She has given me a side gate key for access, sweet as pie now.
3. No problems whatsoever, pays promptly.
4. Poor payer, dropped
5. Very Small Commercial (£20):- I was dropped by her Eastern European husband for a cheaper w/c who didn't turn up. HAHAHA!
She was livid with him (her husband) told him off and begged me to go back, which I did for an extra £5. Sweet as can be (and very attractive, which is nice!
)
So my experience is mixed but I have had a higher proportion of probs so am careful when I am approached.
