My Costco account was started overseas. We have a business account, and it allows us to add employees for an additional US$6 each. So, every year we ask who wants in, and we split the total cost of the renewal. We get no Executive cash-back, but it keeps our friends and employees happy.
I live alone for most of the year in the US, but I go to Costco about once a week for three to five items.
Due to my guerrilla-style of shopping (get in fast and get out), the food give-aways and people parking their carts in the middle of the aisles makes me crazy as well. I look forward to Halloween nights where I strip naked and run up and down the aisles... no one minds because they're not there, or they're doing the same thing. Also, the stores actually open 15mins before the stated opening time, so I show up early on the weekends and I'm out before they actually open.
Same with gas... it opens hours before the store actually opens, and there's no line between 5:30am and 8:30am.
I love Costco.
