It certainly is. One WL owed around $150,000 after borrowing it from the boss to gamble. She won about $60,000 on the pokies (lightning link), blew it all within a week or two then borrowed more money.
No matter how nice or friendly a WL is, they will always take advantage of punters who cave in to their demands or hear their sob stories. One J WL who has since returned to Japan quoted me $5,000 for 24 hours with her. No fucking way would I pay that type of money. Blocked and deleted.
