Understanding the behaviour of at + x minutes

Question

When I run

echo "hello" | at now + 7 minutes

I get the following output -

job 2 at 2016-12-11 05:06

However when I use

bash txt | at now + 7 minutes

It starts executing immediately.

The bash command is invoking the script now and doesn't have anything to pipe to the at command.

cat txt | at now + 7 minutes

will pass the lines of the bash script to at
