Trying to access instance variable from service class

service.rb

class MyService
  def initialize user, card, pricing_service
    @user = user
  end
end

# Initialize
MyService.new(current_user)

# Trying to return value outside controller, maybe in the console for example
x = MyService.new(User.first)???
x.instance_variables #returns an array containing [[0] :@user]

# is there a way to actually get that record?
# What I tried
x[@user]
x[:user]
x["user"]
x[0]
