I found this while surfing the internet. Very funny! Can you see what is wrong?

A friend of mine sent this to me:
Okay so this is how I imagine this conversation went:
Walmart Employee: “Hello ‘dis be Walmarts, how can I help you?”
Customer: ” I would like to order a cake for a going away party this week.”
Walmart Employee: “What you want on the cake?”
Customer: “Best Wishes Suzanne” and underneath that “We will miss you”.
アメリカのスーパーに電話した。ウォルマートの人はちょと訛っているだな。
お別れ会のケーキを注文したけどウォルマートの人は聞き間違い。。。
and underneath that=その下に書いて!
スペルも間違えたよ!
信じられない。
