I'm sure I've mentioned this before but...
My gmail account is in the traditional format firstname.lastname@gmail. My name isn't rare-rare but not desperately common.
To my endless amusement there is a freelance movie cameraman in NYC, an unemployed accountant in Maryland, a church administrator in North Carolina, a retired dude in Florida, an IT support worker in Texas, a gas pipeline engineer with really interesting leisure interests in Canada, a student in Nottingham and a surfbum in Perth, all of whom share my name and are incapable of providing their correct email address to organisations they're dealing with.
The mails I receive are interesting enough. The inability of many organisations to deal with me informing them that they have the wrong address is really funny.
