Some of my best customers are Polish. I always get greeted with a smile, always very appreciative of the service, more often than not they slip an extra €5 into my hand, and very trusting too. I cleaned a house for a Polish lady this morning, charged €25 as it was a first clean and she tried to pay me €40!
Another first clean 3 weeks ago, who has never met me and only communicated via text or e-mail, hid her back door key and asked me to clean the insides too, and left payment on the dining room table for me!
