hahahahahahah................. sorry Shok, great story and funny, but I think you know you made a faux pas.
To the person who's never heard of the Hispanic gardener stereotype what rock have you been living under? It's probably the Number 1 stereotype for Hispanic men.
If you went to a Jewish home for a child's birthday party and everybody was Jewish - and while opening the presents the kid got his third piggy bank you commented to 50 adults of the Jewish persuasion "Man you guys are teaching him early huh?" - you'd have received the same reaction. Probably A LOT worse.
very funny story tho.
<------ some people think this is racist
